How exactly is LMTP proxying supposed to work? According to the example on http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy I'm only seeing "proxy" in the password_query statements. But LMTP never sends a password. IMAP Proxying is working OK: Sep 24 12:51:09 imap-login: Info: proxy(ralf.hildebrandt at charite.de): started proxying to dovecot.charite.de:993:

For archiving purposes I'm delivering all addresses to the same mdbox: like this: passdb { driver = passwd-file args = username_format=%u /etc/dovecot/passwd } userdb { driver = static args = uid=1000 gid=1000 home=/home/copymail allow_all_users=yes } Yet I'm getting this: Jan 3 19:03:27 mail postfix/lmtp[29378]: 3THjg02wfWzFvmL: to=<firstname.lastname at

I need to find all mails with a certain numerical range in my quarantine: X-Spam-Status: No, score=4.5 tagged_above=2 required=4.6 ... Assume I'd be looking for 4.5-6.0; so I tried searching for doveadm import -u restore mdbox:/home/quarantine/mdbox "" \ mailbox INBOX header X-Spam-Status "No, score=4.5" doveadm import -u restore mdbox:/home/quarantine/mdbox

My users say that "greetings of the day" occurs in academic spam a lot. Since I don't trust my users, I opted to verify this bold claim. But how do I search for a sequence of multiple words? doveadm import -u restore at backup.invalid mdbox:/home/copymail/mdbox "" mailbox INBOX BODY "Greetings of the day" doveadm import -u restore at backup.invalid

Today I was looking for some spam and issued this command: ========================================================== doveadm import -u restore at backup.invalid mdbox:/home/copymail2/mdbox INBOX header Reply-To bixrs.com Then I immediately got a crash: doveadm(restore at backup.invalid): Panic: file mail-index-util.c: line 10 (mail_index_uint32_to_offset): assertion failed: (offset <

We're using dovecot (via LMTP) as a backup for all incoming mail. I upgraded from 2.3.6 to 2.3.7 on the 12th: 2019-07-12 14:35:44 upgrade dovecot-imapd:amd64 2:2.3.6-2~bionic 2:2.3.7-8~bionic and it seems that 2.3.7 is slower than 2.3.6 -- mail to the backup IMAP box is suddenly taking quite some time to get delivered and is piling up in the queue. doveconf -n: ============

I set up system copying all mails to a backup system. This used to work without a hitch - now in the last few days mails would pile up in the Postfix Queue, waiting to be delivered using the lmtp transport into dovecot. So dovecot was being slow, but why? After all, nothing changed. After reading some articles on stackoverflow I found a way of finding out which file gets the most IO: % sysdig

I'm getting this in the log when proxying IMAP (three "valid certificate" messages, two "Invalid certificate" messages) Why is dovecot (acting as a proxy to another dovecot instance here) not recognizing the StartCom Extended Validation Server CA? .

I have deduplication active in my first mdbox: type mailbox, but how do I find out how well the deduplication works?

I'm seeing the first occurence of that problem on the 10th of october! I was using (prior to the 10th) : 2.3.0~alpha0-1~auto+371 On the 10th I upgraded (16:04) to:

Some of our users use to login as firstname.lastname or firstname.lastname at charite.de instead of using the "correct" "flastname" login name. In order to get this behaviour a long-gone co-worker wrote an authdaemon.pl, which speaks the courier-authdaemon protocol. How can I emulate this behaviour with dovecot? Basically, all I need is a usernamen mapping ala:
