Hi, I have one pop3 client who has three computers, and he has Outlook XP on two, and 2003 on the third. They are all set to leave a copy of messages on the server, and that causes a duplicate message for every message he gets. I then can tell him to uncheck the "leave a copy on the server" box, and pop his mail, and the duplicates will go away for two or three days, only to start up again. I have a stock Fedora Core 2 server with dovecot and Sendmail. I do a nightly yum, so as to stay up2date. My version of dovecot is 1.0-test42. Has anyone else seen this issue? What can I do to fix it, short of permanently unchecking that box in Outlook? (The user is my boss, and he likes to get his email on all three computers...) -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

You can use following variables: # # %v - Mailbox UIDVALIDITY # %u - Mail UID # %m - MD5 sum of the mailbox headers in hex (mbox only) # %f - filename (maildir only) # # Note that Outlook 2003 seems to have problems with %v.%u format which is # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. #pop3_uidl_format = %v.%u Alternatively if test42 doesn't have the setting and you want to patch it instead of upgrading, you can use a patch that is for 0.99.x, but similar fix should work with test42: http://dovecot.org/patches/outlook-pop3-uidl.diff -------------- next part -------------- A non-text attachment was scrubbed...
