Hey everyone, Our school district has seen an enormous increase in the number of legitimate and spam email messages in the last year. Compared to October 2003, last month saw an increase of 35% for legitimate email. The number of messages trapped by our spam filters went from 75,000 in October 2003 to over 1,000,000 last month alone. Our existing system, a PowerMac G4 running EIMS (Eudora Internet Mail Server) on OS 9, is buckling under the strain. We have a dual-G5 Xserve on the way and plan to move all of our 2,000 users to Postfix running on OS X. Most of our users are accessing their email via POP, although some are using IMAP. Most of them download their messages to their computers, but quite a few leave them on the server. We also have a mixture of OS 9, OS X, and Windows XP machines around here. I was hoping that some of you may have experience moving a large number of email users from one system to another. What did you do with incoming messages during the transition time? How did you move the mailboxes from the old system to the new one? I'm just hoping to glean some wisdom from the gnarly old mail server admins on the list in order to head off as many problems as possible. Our existing system is on life support and I'm afraid we don't have a lot of time to make this switch. -Tim -- Tim Wilson Twin Cities, Minnesota, USA Educational technology guy, Linux and OS X fan, Grad. student, Daddy mailto: wilson at visi.com aim: tis270 public key: 0x8C0F8813 _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota Help beta test TCLUG's potential new home: http://plone.mn-linux.org Got pictures for TCLUG?
