You might want to enable mail_log plugin for imap/pop3 protocols only.
protocol imap {
mail_plugins = $mail_plugins mail_log
}
protocol pop3 {
mail_plugins = $mail_plugins mail_log
}

Re: Dovecot 2.3.3 Mailbox does not exist
Dear Martin,
Many thanks for the advise and yes I agree I should set debug mode to on
and work from there.
Thanks!

Dovecot Logging and Shell Script Hang
Greetings, We have a PHP based shell script that runs a doveadm backup routine. This script was running just fine, and then we turned on more logging for Dovecot (enabled the mail_log plugin). For some reason, once this was done, the shell script would run for a few minutes and then hang, as it added more log messages to the dsync STDOUT. Once the mail_log plugin was disabled, it ran without hanging. Is there any way to run doveadm and temporarily suspend the mail_log plugin? Or is there a better way to do this? Thanks for the insights. Asai
Unexpected behavior with sieve_vacation_to_header_ignore_envelope = yes
Hello,
we face an issue with the vacation extension of pigeonhole. Our upstream
mail server (from which we pull our E-Mails with POP3) uses SPF and
performs a SRS re-write of the Return Path. Once the mail is processed
via our local postfix, it is delivered via dovecot deliver (using the
lda). When the recipient has a vacation rule enabled in sieve, the
out-of-office note cannot be sent, as pigeonhole tries to use the
Return-Path (which is not accepted as sender by the mail server).
We are using the following dovecot / pigeonhole versions:
dovecot-2.3.2.1
dovecot-pigeonhole-0.5.2
As of my understanding, the problem was addressed in pigeonhole version
v0.4.21 by introducing the sieve_vacation_to_header_ignore_envelope
setting. Anyway - even when this is set to "yes" pigeonhole still uses
the Return-Path instead of the "From:" header which I had expected:
Feb 27 13:22:26 mail dovecot:
lda(customer)<48383><3o+yOQGBdlz/vAAAZU03Dg>: Error: sieve:
msgid=: failed to
send vacation response to
SRS0=gwGXg6ad=RC=petermann-it.de=matth...@example.com: returned error> (temporary error)
Are my expectations wrong or did I miss some precondition?
Best regards,
Matthias

Re: performance issue with UID SEARCH
Without FTS, dovecot needs to open *each* and *every* email when doing text searches, which is understandably rather slow process.

I don't find any good guide and everything I have found is some years old. Has any of you done a recent integration with CAS and can share the details ? I can't help you with rouncube part (because we use horde as webmail), but dovecot we have configured with pam_cas module. The idea is that horde pass a PGT as user password, and with PAM dovecot server checks it. -- Angel L.

Re: Linking mailboxes
So did you get everything fixed up ? > doveadm(lightdm): Error: Can't open mailbox Storage/Email: stat(/run/media/computer/Storage/Email/tmp) failed: Permission denied (euid=976(lightdm) egid=976(lightdm) missing +x perm: /run/media/computer/Storage/Email, dir owned by 5000:5000 mode=0700) Now it's another user that needs to access that directory (lightdm, euid=976). I would add lightdm to the vmail group and make the directory group readable and accessible, so chmod g+rx /run/media/computer/Storage/Email and any other folder it's complaining about. Yassine.
