  2. Spam/Virus Blocking • Blocking umn.edu and other “protected” sites if we mark them “insecure” (still protected from other blocks) • Checking (but not yet blocking) based on the XBL (xbl.spamhaus.org) • Now treating “inactive” MTA same as “never seen before”

  3. Spam/Virus Blocking • Require rDNS for all but 200 /16 nets • About 50 each in 207, 208, 209, 216 /8’s • Plenty of manual, semiautomatic exceptions • AOL “Feedback Loop” and forwarding heck • Investigating ClamAV • LISTSERV • Outgoing email (smtp, smtp-gw, relay)

  7. Phase-out of non-SSL services

  8. Phase-out of non-SSL services

  9. Phase-out of non-SSL services • Only SMTP stats now; telnet, FTP, POP, IMAP coming next month • Finding misconfigured systems (should be using relay.tc.umn.edu), viruses–don’t want to count those! • Email notifications slated for Nov, Feb

  10. Hardware Upgrades • Email servers • Two servers on SAN with 1GB quotas • Two more, and premium/interactive (garnet) on SAN by start of Fall Semester • 1GB quotas for everyone by start of Fall! • Solaris 9—prerequisite for longer Internet passwords…

  11. Hardware Upgrades • MX servers for umn.edu • 3 x Sun V210 • One running in production since Thu • Outgoing SMTP (smtp.umn.edu, smtp-gw, relay) • 3 x Sun V210 • Not hurting for capacity here, so will phase in more slowly

  12. Hardware Upgrades • Internet Services • www.umn.edu • x500.umn.edu (CAH) • *.email.umn.edu DNS • RADIUS • X.500 lookups (finger, gopher, whois, ph) • Also 3 x Sun V210

  13. Hardware Upgrades • X.500 backend database server • Sun V240 • Last Solaris 2.6 machine!

  14. Software Upgrades • LISTSERV 1.8e • Niftier web interface • Web-based moderation • List configuration wizards • Content filtering • Remove vacation messages • Filter/restrict type of attachments • Precedence: list in headers ;) • BIND 8.4.4

  15. Software Upgrades • Apache 1.3.31/mod_ssl 2.8.19 • PHP 4.3.8 • Supports GD, mysql, openssl, XSLT (latter doesn’t work?) • 5.0 just came out—too new • Lynx 2.8.5 (help no longer a porn portal) • X.500 directory (in test; awaiting vendor bugfix before production)

  16. Lyris • Massmailing server • Right now just “looking at it” • IS would run server, U Relations would likely manage it (assign permissions, etc.) • Would remove some workload off IS staff for doing massmailings

  17. PKI • Pilot scheduled to begin late Sept • More details at Sept techc-email and net-people
