Can anyone here help me out with a client side Outlook issue? I know outlook is a horrible imap client :(
We intermittently have a problem where mail gets "stuck" in Outlook users' outboxes.
Might have anything to do with dovecot? Is there anyway I can troubleshoot this server side? Are there any settings I can tweak?
We have a new and an old dovecot server (see below) and both exhibit the same behavior (occasionally) for heavy mail users.
We haven't ruled out a layer 2 issue but nor have we found one....
If anyone has any ideas (other than suggesting a different email client), they'd be much appreciated.
Dovecot version(s) 1.19 & 0.99.11
Configuration from 1.19:
1.1.9: /usr/local/etc/dovecot.conf
OS: Linux 2.6.9-78.0.13.ELsmp i686 Red Hat Enterprise Linux ES release
4 (Nahant Update 7) ext3 syslog_facility: local0 ssl_cert_file: /usr/local/etc/ssl/**************** ssl_key_file: /usr/local/etc/ssl/***************** disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_write_locks: fcntl auth default: debug: yes passdb: driver: pam userdb: driver: passwd
Most of the time that my users run across this it is one of three things;
Outlook is locked up and a re-start fixes it (sometimes an Outlook restart, sometimes it takes a reboot).
Bad e-mail address. It only takes one invalid address to leave the file in the outbox.
Full PST file. Older PST files and those that are associated with IMAP use are limited to 2 GB of data. Outlook caches a lot of info about IMAP use, and also stores local copies of read messages. Sometimes a compaction will free space, and sometimes not. Or you create new PST files and move things around.
