  1. E-mail Technical Coordinators Meeting Chris Bongaarts Steve Siirila September 7, 2005

  2. Outages • E-mail server (peridot) failed on August 26th (1508-1831) due to a memory failure • Mail spool full on Morris E-mail server on August 28th due to a mass mailing involving a 14MB message

  3. Win2K UMN.EDU Forest Decommissioned • Remaining domain controllers for the UMN.EDU forest shut down Aug 29th • Talk to Kevin DeJong (ADCS) if you are interested in having your forest managed by OIT (*.ad.umn.edu)

  4. E-mail Hardware Upgrades • 2 Sun V890 servers with 19K users each • 4 Sun V440 servers with 10K users each • 1 Sun V440 server with 10K non-SSL users • 1 Sun V440 server with 3K interactive users • 1 Sun V240 server with 50K+ inactive users • 1 Sun E450 server with 5K Morris users • Total: 10 servers with ~150K users

  5. Inbox Auto-Filing • Users with an Inbox over 20MB will receive an introductory message once • Users whose mailboxes have any messages archived will be notified each time this takes place

  6. Inbox Auto-Filing • Preliminary list of ALL eligible users will be available if sufficient interest • Letters to eligible users to be sent out weekly beginning week of Sept 18th • Number of users will be limited for the first few weeks • List of users who were sent letters can be sent to technical coordinators

  7. Phase-out of clear-text passwords • Moving users at a rate of 20 per day to secure E-mail servers as they are determined to be set up securely • Users can choose to be moved (happens within 24 hours)

  8. Unauthenticated SMTP gateway phase-out • Users should be using the service smtp.umn.edu for outgoing e-mail • Servers/devices unable to do SMTP authentication should be using the service relay.tc.umn.edu instead • No phase-out timeline established • To check your server settings, send an e-mail to: ssl-test@umn.edu

  9. Migrating E-mail Servers from Department to Central • Internet ID synchronization • Individual user forwarding to central • Domain-specific e-mail address mapping at the SMTP level, e.g.: • webmaster@dept.umn.edu -> deptweb … • jsmith@dept.umn.edu -> smith999 … • bob@dept.umn.edu -> REJECT • Switching MX record to point to central

  10. AOL Blocking UMN e-mail • AOL blocking UMN due to excessive number of spam reports by its users • Possible solutions: • Forbid forwarding to AOL (maybe only forbid students?) • Require strictest spam blocking for forwarders, or forbid forwarding for those who allow all mail • Disable forward for complainers • Other suggestions?
