September 2009 Monthly Activity Report
1) Resolved several LISTSERV issues. Messages sent from lists with duplicate subscriber addresses were being rejected after Proofpoint upgrade. Appears that something changed in new version of Sendmail on Proofpoint that disallows duplicate recipient addresses. Resolved by creatng script to identify lists with duplicate subscriber addresses and removing them. Used similar script to identify lists with malformed subscriber addresses or invalid subscriber addresses and removed them.
2) Upgraded Proofpoint from release 5.0.3 to lastest release. This includues the addition of the Smart Search module and many bug fixes.
3) Gmail for Life. The new provisioning process for VUmailguard is progressing nicely and should be finished soon if no operation issues arise.
4) Worked in conjuction with ITS Security on several incidences e.g. daily scams, threats, compromised hosts and accounts, etc. Note the phishing scams seem to be on the rise.
5) Managed abuse@v.e, postmaster@v.e., vumailguard-cmd@v.e., vumailguard-review@v.e. and listmaster@v.e. mailboxes. Monitored abuse@v.e. and vumailguard-review@v.e. for daily reports of spam false negatives. Investigated over 100 spam false negatives.
6) Performed daily management of mail queues on mailgates. Removed thousands of undeliverable messages daily in order to keep queues “clean”. Review messaging reports daily in order to spot trends, abuse, etc. and took appropriate action to deter threats.
7) Created monthly Email metrics report for dashboard. See \\vuspacegroups\ITS\common\dashboard\New Dashboard\Application Hosting.
Worked on an assortment of odd and challenging helpdesk tickets
July 2009 Monthly Activity Report
1) Resolved another LISTSERV issue. Found that a configuration option value was carried over from the eval configuration. With lists configured to require owner approval for subscriptions, the URL presented in the approval message contained a malformed email address. This resulted in an invalid subscriber address being added to the list. Issue has been resolved by correcting the configuration option value.
2) Created various scripts to gather inoformation related to the Exchange 2007 project.
3) Gmail for Life. Nothing new to report. Awaiting a source in order to begin testing of new provisioning process.
4) Legacy Email. Provided assistance in order to configured the VM SMTP replacements and configuring a test environment. Assisted with validation testing.
5) New Acquistion. We are now routing email for the domains associated with the new VUMC acquisition, The CardiacCenter of Murfreesboro.
6) New Acquistion. As new employees from Franklin Bone and Joint activate their user ids, Exchange 2007 mailboxes are being created. This has almost completed. They have elected to initially forward email but at a date yet to be determined, they wish to route email for their domain also.
7) Worked in conjuction with ITS Security on several incidences e.g. daily scams, threats, compromised hosts and accounts, etc. Note the phishing scams seem to be on the rise.
8) Managed abuse@v.e, postmaster@v.e., vumailguard-cmd@v.e., vumailguard-review@v.e. and listmaster@v.e. mailboxes. Monitored abuse@v.e. and vumailguard-review@v.e. for daily reports of spam false negatives. Investigated over 100 spam false negatives.

June 2009 Monthly Activity Report
1) Working with L-Soft and other team members gathered and provided metrics in order to debug issues with LISTSERV performance. Based upon data L-Soft recommended demoing the LISTSERV high performance option (HPO). Tests of HPO demo license in dev server resulted in much improved performance. Tests of HPO demo license in production resulted in much improved performance as well.
2) Created script to provide ACLs for all group mailboxes and determine which mailboxes were accessed over the life of the logs files.
3) Created script to provide info about which IMAP mailboxes were accessed over the life of the log files.
4) Gmail for Life. Nothing new to report. Awaiting a source in order to begin testing of new provisioning process.
5) Legacy Email. Provided assistance in order to configured the VM SMTP replacements and configuring a test environment.

May 2009 Monthly Activity Report
1) Network reconfiguration of vanderbilt_production mailgates was incomplete. This change was related to issues where adding hosts and DNS entries via the Admin GUI can cause the hosts entries to be deleted or adding DNS servers can lock up the host. The issues can be resolved by assuring NIC#1 is configured on the same VLAN as the gateway as proven in the vanderbilt_lab cluster. Ran into an issue with mailgate02. It would not save the new configuration when reconfigurng via the Admin GUI or console. Opened call with Proofpoint and provided logs. They have recommended removing the agent from the cluster and reconfiguring then adding the agent back to the cluster. Note maillgate02 and mailgate03 reconifguration was not completed during the change window and must be rescheduled.
2) Deployment and configuration of LISTSERV development server has been completed with one exception. DNS MX record must be created.
3) Found method to provide list of all group mailboxes, their ACLS, and the last time they were accessed. Have supplied data to project manager.
4) Gmail for Life. Met with iDev team in order to determine a strategy for populating the Proofpoint user repository used for sapm policy assigment and recipieint verification. Provided them with user repository export and configuration documentation so that options could be explored.
5) Worked in conjuction with ITS Security on several incidences e.g. daily scams, threats, compromised hosts and accounts, etc.
6) Managed abuse@v.e, postmaster@v.e., vumailguard-cmd@v.e., vumailguard-review@v.e. and listmaster@v.e. mailboxes. Monitored abuse@v.e. and vumailguard-review@v.e. for daily reports of spam false negatives. Investigated over 100 spam false negatives.
7) Performed daily management of mail queues on mailgates. Removed hundreds of undeliverable messages daily in order to keep queues “clean”. Review messaging reports daily in order to spot trends, abuse, etc. and took appropriate action to deter threats.
8) Created monthly Email metrics report for dashboard. See \\vuspacegroups\ITS\common\dashboard\New Dashboard\Application Hosting.
9) Worked on an assortment of odd and challenging helpdesk tickets.
1) Completed testing of mailgate upgrade process in vanderbilt_lab cluster. Includes inspection of policies and rules, LDAP imports, etc.
2) Started deployment and configuration of LISTSERV development server. Will be completed in early May 2009.
3) Worked in conjuction with ITS Security on several incidences e.g. daily scams, threats, compromised hosts and accounts, etc.
4) Managed abuse@v.e, postmaster@v.e., vumailguard-cmd@v.e., vumailguard-review@v.e. and listmaster@v.e. mailboxes. Monitored abuse@v.e. and vumailguard-review@v.e. for daily reports of spam false negatives. Investigated over 100 spam false negatives.
5) Performed daily management of mail queues on mailgates. Removed hundreds of undeliverable messages daily in order to keep queues “clean”. Review messaging reports daily in order to spot trends, abuse, etc. and took appropriate action to deter threats.
6) Created monthly Email metrics report for dashboard. See \\vuspacegroups\ITS\common\dashboard\New Dashboard\Application Hosting.
7) Worked on an assortment of odd and challenging helpdesk tickets.
1) Proofpoint vanderbilt_production cluster master replacment. 1) Two older appliances were lifecycle and replaced with VMs. Before doing so, the VMs were reconfigured in order to add additional RAM and CPUs. 2) The upgrade from version 5.0.3 to 5.5.4 was tested in the lab cluster. After the upgrade, discovered an issue where a rule caused message routing to not work. Was able to reconfigure the rule in order to resolve the issue. 2) Before upgrading the production cluster, will test funtionality similar in production to assure it is working properly and that any configuration changes that occurred during the upgrade have no adverse impact. 3) The Smart Search module was included in the lab upgrade and testing of this module has begun.
2) Project for mailing list replacement. The migration from Majordomo to LISTSERV was completed on 3/4/2009. After the migration, some adjustments have been made in order to a) tune the LISTSERV configuration for better performance b) plug a security hole that was missed c) reconfigure several lists in order to assure quickest delivery and d) reconfigured lists ported over from Majordomo that had connfigurations that worked differently in LISTSERV. Despite best efforts, the project team could not find owners for over 100 lists although the lists had been active in the past year. Those lists were migrated with a temporary owner, listmaster. Currently those lists are being managed by listmaster, a task I have been performing. A few remaining tasks has not been completed. a) The development server has not been deployed yet. b) scripts for various list operations are being created e.g. globally changing list configurations if required and gathering list info for various reports beneficial for administration. Also have been performing daily monitoring of LISTSERV queues in order to assure there is no queue backup, an indication that the server may require additional tuning.
3) Project to implement smtp and e-mail authentication. This project is set to resume once Chris Contos completes a couple other projects.
4) The VUmailguard FAQ has been updated to include documentation about how messages are processed and an explanation about all modules and technologies used to mitigate threats. Additional content will be added at a future date will include a) a brief explanation of how email works b) tips for avoiding spam c) inclusion of a tool to obfuscate email addresses that will be published on web sites as a deterrent against web crawlers that harvest email addresses published on web sites in plain text and d) link to VUMailguard Blocked file types and attachments must be added. It was erroneously deleted and we are attempting to find a backup copy. See https://its.vanderbilt.edu/stakeholders/blockedtypes.php.
5) Found three bugs in Proofpoint version 5.0.3. a) Host override function does not work in Admin GUI. This updates the /etc/hosts file. b) Adding tertiary DNS server causes network interfaces to lock. Workaround is to manually edit /etc/resolv.conf and named.conf files. c) SPF records with include: mechanism can cause sporadic erroneous SPF failures. Bug fix is included in version 5.5.4. Workaround is to spfsafe list host/domain where applicable.
While testiing upgrade of lab cluster from 5.0.3 to 5.5.4, discovered /etc/hosts file entries were deleted on the node being upgraded which caused the upgrade to hang. Found a workaround related to an OS bug that requires the first NIC to be configure on the same VLAN as the gateway. This change resolves the issues with the network interfaces where making changes to the DNS hosts or /etc/hosts files via the Admin GUI or during an upgrade causes the host file entries to be deleted. Note a change record has been requested in order to reconfigured all nodes in the production cluster before performing an upgrade from 5.0.3 to 5.5.4.
6) Worked in conjuction with ITS Security on several incidences e.g. daily scams, threats, compromised hosts, and SWEs, etc. There has been a recent increase in phishing spam and spam in general. Users have been reporting more spam false negatives.
7) Managed abuse@v.e, postmaster@v.e., vumailguard-cmd@v.e., vumailguard-review@v.e. and listmaster@v.e. mailboxes. Monitored abuse@v.e. and vumailguard-review@v.e. for daily reports of spam false negatives. Investigated over 100 spam false negatives.
8) Performed daily management of mail queues on mailgates. Removed hundreds of undeliverable messages daily in order to keep queues “clean”. Review messaging reports daily in order to spot trends, abuse, etc. and took appropriate action to deter threats.

January 2009 Monthly Activitiy Report
1) Proofpoint vanderbilt_production cluster master replacment. The vanderbilt_production cluster master was successfully replaced on 1/21/09.
2) Project for mailing list replacement. a) The automain list tool process has been ported. This was one of the last tools to be ported from Majordomo. b) A script was written in order to obtain all options and values from lists on Majordomo. This will assist with the migration process of Majordomo options to LISTSERV keywords values. c) Tentavtive migration from Majordomo to LISTSERV is scheduled for spring break.
3) Project to implement smtp and e-mail authentication. This project is currently on hold but has been transferred from Kate Gilbreath to Chris Contos.
4) The VUmailguard FAQ has been updated to include documentation about how messages are processed and an explanation about all modules and technologies used to mitigate threats.

December 2008 Monthly Activitiy Report
1) Proofpoint vanderbilt_production cluster master replacment. The new Proofpoint master arrived, was racked, and configured on the network. Currently am awaiting CSM and firewall configuration in order to complete configuration of the master (The new master must have a public IP in order to activate the cluster). Once the master configuration has been completed , a security scan will be performed. After successful completion of the security scan, several tests will be conducted to include adding physical and virtual agents to the new master, a test run of the migration involving moving databases from the old to new master, etc. This process will be documented and used as a template during the actual migration of the master. Note that Proofpoint Professional Services availability is very limited since that service is only staffed by two people. We will be meeting with them in order to determine a time table to complete this project.
2) Project for mailing list replacement. a) Several strategies in order to port the Majordomo auto-maintain tool were discussed and tested including using the LISTSERV bulk add and delete feature as well as Dynamic Queries. In the short term, the bulk add and delete feature provides the quickest and most direct port of the functionality in the Majordomo auto-maintain tool. There are still aspects of Dymanic Query feature that are not understood and appear to not proivde the same functionality of the auto-maintain tool. Further testing will determine if Dynamic Queries can be used for the auto-maintain tool and how they can be used in the provisioning process as a future enhancement.
Tasks yet completed include: a) completion of the VU LISTSERV Installation and Configuration Guide b) completion of the VU LISTSERV Admin FAQ c) creation of a script to audit LISTSERV lists for invalid owner email addresses, to assure listmaster@v.e. address is included as owner in all lists, and to assure owners have not been configured as quiet owners (This is a prerequiste of the ALL-REQUEST alias) d) migration from Majordomo to LISTSERV.
3) Project to add vanity domain, newlightimaging.com. This project was completed on 12/10/08.
4) Project to implement smtp and e-mail authentication. This project is currently on hold but has been transferred from Kate Gilbreath to Chris Contos.
5) The VUmailguard FAQ has been updated to include documentation about how messages are processed and an explanation about all modules and technologies used to mitigate threats. Additional content will be added at a future date will include a) a brief explanation of how email works b) tips for avoiding spam c) inclusion of a tool to obfuscate email addresses that will be published on web sites as a deterrent against web crawlers that harvest email addresses published on web sites in plain text and d) link to VUMailguard Blocked file types and attachments must be added. It was erroneously deleted and we are attempting to find a backup copy. See https://its.vanderbilt.edu/stakeholders/blockedtypes.php.
6) Investigated the impact of raising the message size limit to some undetermined value and the impact on the messaging system.
All systems allow configuration of a message size limit and only VUmailgaurd allows configuration of an attachment size limit. Exchange is currently configured w/ a 20 MB outbound and 15 MB inbound, VUmail is currently configured w/ a 15 MB inbound and outbound message size limit, VUgmail is currently configured w/ a 20 MB inbound and outbound message size limit and Majordomo is currently configured with a 15 MB message size limit. VUmailguard is configured with a 30 MB message size limt and 20 MB attachment size limit. All systems should be synchronized to the same message size limit. Recommendation is to set the message size limit on all systems to 20 MB with a 15 MB attachment size limit where applicable in the short term. VUMC NCS is reluctant to raise the limit any further due to hard drive space and hardware constraints. They would be more receptive after migrating from Exchange 2003 to 2007. Recommendated message size limit after migration would be 30 MB message size limit with 20 MB attachment size limit. Note we have no control over the VUgmail message size limit.
7) Working in conjuction with ITS Security, we have discovered a growing botnet that has created negative impact upon Vanderbilt University’s email reputation. Possible solutions had previously been discussed as part of the smtp and email authentication project. continue identifying offending hosts and reporting them to ITS Security. The issue has lessened particularly since the holiday break.
8) Worked in conjuction with ITS Security on several incidences e.g. daily scams, threats, compromised hosts, and SWEs, etc.
9) Managed abuse@v.e, postmaster@v.e., and listmaster@v.e. mailboxes. Monitored abuse@v.e. and vumailguard-review@v.e. for daily reports of spam false negatives. Created or edited Proofpoint rules in order to deter several threats. Investigated over 100 spam false negatives.
10) Perform daily management of mail queues on mailgates. Remove hundreds of undeliverable messages daily in order to keep queues “clean”. Review messaging reports daily in order to spot trends, abuse, etc. and took appropriate action to deter threats.

August 2008 Monthly Activitiy Report
1) Worked on an assortment of odd, challenging, and familiar helpdesk tickets.
2) After upgrading Proofpoint vanderbilt_production cluster from version 4.0.7.67 to 5.0.3.103, there continued to be database issue. The cron jobs that collect and expire logs was not keeping up. Proofpoint Support made several changes and finally the all log files are being processed daily. A new issue has been discovered though. It appears some data for historical Summary Dashboard reports may be erroneous. I am working with Proofpoint Support in order to debug.
3) Discovered issue where uc2k7.vanderbilt.edu email routing was improperly configured. Made recommendation to resolve issue and implemented change on 9/26/08.
4) Project for mailing list replacement. a) The loaders and VSA tools have been completed less the incorporation of the list header templates. b) The list header templates were completed on 9/26/08. c) Troy completed customization of the GUI interface in order to include the VU branding but it must be approved by Cindy Frank. d) Have spent considerable time with L-Soft debugging issues with LDAP AUTH. Bug was found that was supposedly corrected by latest revision of LISTSERV 15.5. Upgraded to latest revision but issues still persist. Continue to work with L-Soft in order to resolve issue. e) Completed starup script. f) Pilot will begin as soon as LDAP AUTH issue has been resolved. g) Since Kate is leaving on 10/10/08, Chris Contos will be new PM. i) Outstanding items include LDAP AUTH, creation of scripts in order to expire log files so they do not grow w/o bound, incorporation of list header templates in loaders, possible cookie expiration issue, tuning if required, migrating lists from Majordomo, reconfiguring listserv for production, installing a warm backup server, and documenting the build process.
5) Project to implement smtp and e-mail authentication. Project is currently on hold.
6) Discovered link to VUMailguard Blocked file types and attachments was erroneously deleted. See https://its.vanderbilt.edu/stakeholders/blockedtypes.php. I am working to see if I can obtain a backup so the link can be put back into place.
7) Worked in conjuction with ITS Security on several incidences e.g. scams, threats, compromised hosts, and SWEs, etc.
8) Managed abuse@v.e and postmaster@v.e. mailboxes. Monitored abuse@v.e. and vumailguard-review@v.e. for daily reports of spam false negatives. Created or edited Proofpoint rules in order to deter several threats. Investigated over 100 spam false negatives.

10) Created monthly Email metrics report for dashboard. See \\vuspacegroups\ITS\common\dashboard\New Dashboard\Application Hosting.
11) Attended course on Upgrading Your Skills from Microsoft Exchange Server 2003 to Microsoft Exchange Server 2007. One specific outcome was I found out that the antispam, antivirus features of the Microsoft Exchange Server 2007 Edge Server is far from usable in an organization as large as Vanderbilt University and has some features that do not meet recognized standards. Many applications would be broken if certain features were enabled. Also attended 2 day course on Monitoring and Troubleshooting Microsoft Exchange Server 2007. Although some things have changed considerably (Powershell is required to configure most of the features in Exchange Server 2007 and also must be used to perform much of the debugging.
