Hi, I'm in the process of upgrading from dovecot v1.1 to dovecot 2. We fetch uid/gid user information from a database and also use post-login scripting with mail_drop_priv_before_exec = yes which means the postlogin script is executed with the permissions of the user we have found in the database. According to the dovecot2 wiki page, to get this behaviour in version 2 we have to set the post-login script to run as root and then su to the user. This seems a bit of a strange...

...#39;s contents refer to a PID that, by the time I see the lockfile, doesn't exist. It appears that dovecot is leaving behind the lock files, after exiting with a signal 6 (sometimes 11) and leaving behind messages in /var/log/maillog (and the end of this message). In dovecot.conf I have mail_drop_priv_before_exec = no, but I can't find the core file that I would expect it to dump, so I can't give you a backtrace. Hopefully the assertion in /var/log/maillog is enough. With ~/.mail/Cron perpetually locked, I'm not able to receive mail in this folder, and with any IMAP client that tries to a...

Hey all: Was playing around with kill -11 on dovecot processes to see which ones would dump core and which ones wouldn't. If ulimit is correct dovecot and dovecot-auth will dump. If you perform the recommended (Set mail_drop_priv_before_exec = yes in config file) step, imap will also dump core. But I'm unable to force imap-login to dump core. I'm curious if this is possible without the linux kernel patch that's recommended on http://dovecot.org/bugreport.html. (BTW tried the patch on my 2.4.18 kernel but the patch ha...

Manao ahoana, Hello, Bonjour, My Dovecot server has to access the users Maildirs. Maildirs are on a NFS mount that only a user (vmail/500) may read and write. No one else. How to configure Dovecot so that at least disk read-write are performed as a "vmail" user (that I have created with the right attributes)? Is the workaround of changing dovecot's system UID/GID a not-so-bad one?
