Hello,
I recently switched to dovecot 1.1.1 with mbox_snarf from uw-imap with
mbox driver enabled.
The mail is delivered by procmail in /var/spool/mail/user
Most of my users have a file INBOX located in $HOME/mail
The mail is transfered from /var/spool/mail/user to $HOME/mail/INBOX
every time an imap connection is done.
Things are OK with clients like thunderbird or evolution, but with imp
or mostly squirrelmail messages are duplicated (some user reported
that a single message duplicated 50 times !).
Every imap connection (thunderbird or webmail) terminates with a warning :
Timeout leak: 0x4534e0
I 've tried to use fcntl in :
lock_method, mbox_read_locks and mbox_write_locks but things are worse
than traditional dotlocks.
My config on my first server :
sendmail-8.14.1 procmail dovecot 1.1.1
On the second server :
The webmail (imp and squirrelmail, latest versions) is installed on
another server but uses server 1 as imap server.
I 've tried to use an imap proxy (perdition) but without any
improvement as far as this problem is concerned.
I previously used another dovecot server on that machine with an NFS
mount to get /var/spool/mail from the first server with the duplicate
problem too.
I enabled mail_log and there where a bunch of Info messages like this :
dovecot: Jul 11 18:20:11 Info: IMAP(foo): copy: uid=22,
dest=/users/foo/mail/INBOX,
msgid=4877879C.40104@math-info.univ-paris5.fr, size=2223
Any hint ?
Is mbox_snarf considered as stable ?
