Hello Dovecot List, I am a bit of a sysadmin novice and this is my first time emailing, so please let me know if I have left some critical information out. I am supporting a small office network supported primarily by linux servers. All of my users are using dovecot as a pop3 daemon on a centOS 5 box, no IMAP users. Seven users are running outlook 2003 on windows XP, two users are running thunderbird on ubuntu, two are running evolution on ubuntu, and one is running mozilla seamonkey on XP. Emails to the mozilla/seamonkey user are downloading multiple times, but not to any of the other users.
A typical maillog report following this user's mail client pop3 login:
Mar 3 10:37:00 servername dovecot: pop3-login: Login: user=<user>, method=PLAIN, rip=::ffff:192.168.99.13, lip=::ffff:192.168.99.4 Mar 3 10:37:00 servername dovecot: POP3(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (84873 > 84872, seq=2, idx_msgs=3) Mar 3 10:37:01 servername dovecot: POP3(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (84877 > 84872, seq=2, idx_msgs=4) Mar 3 10:37:01 servername dovecot: POP3(user): Disconnected: Logged out top=0/0, retr=1/3364, del=1/1, size=3347
Things I've tried: *adding the following lines to dovecot.conf: protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } *deleting the user's homedir mail directory (including all dovecot index files) *restarting dovecot *changing mail clients: tried outlook express, netscape 4.8, thunderbird on user's PC *restarting the server
All changes resulted in only a brief (1-2hr) cessation of the problem.
I've subscribed for a month or so now and searched the archives, but if I missed a solution to this in there, I apologize. Thanks, Ben Julian
