[ENHANCEMENT] Doveadm HTTP API and the mail-crypt plugin
by Kevin N. 13 Jul '21

13 Jul '21

Hello everybody, I was wondering, are there any plans for the near future to include the mail-crypt plugin related functions, like changing the user key password, into the doveadm http api? It would probably be possible to implement it in a more secure way than any other external ad-hoc solution. Wouldn't it? Cheers, K.

getting rid of the passwd file unknown user messages
by Marc 12 Jul '21

12 Jul '21

I have configured a userdb file, so I can test with some accounts and override settings. But it is a bit annoying getting unkown user messages for the majority of accounts not in this userdb. Is there a way to skip this reporting? dovecot: auth: passwd-file(aaaaaaaaaaaa,X.X.X.X,<lGapvOzGS5tNPz8/>): unknown user

High Availability Dovecot / Roundcube / PostfixAdmin ?
by White, Daniel E. (GSFC-770.0)[NICS] 12 Jul '21

12 Jul '21

This is a new setup, running on RHEL 8 with the latest everything. Has anyone out there set up a high availability pair of Dovecot servers - with Roundcube and PostfixAdmin - successfully ?

Sieve vacation + SRS + forwarded e-mail
by Saarts, Erik 10 Jul '21

10 Jul '21

Hello! Having a problem here and am unable to solve it on my own and even dr Google is unable to help. We have domain A on cloud, from where mail gets forwarded to our local server to domain B. Forwarding is done in SPF-compliant way by using SRS (this part we have no control over). This SRS address ends up in Return-Path header, and sieve vacation replies to this address. This is all absolutely correct, but also useless, as sending mail to SRS address leads nowhere. I've tried to edit headers in sieve before passing control to vacation, but that does not work. I tried modifying Return-Path to the value of X-Original-Sender (both in user's sieve file and using scripts in "sieve_before" parameter). Mail gets delivered with changed headers, but vacation acts upon original headers. Is there a workaround? MTA is postfix (3.1.15), dovecot is version 2.3.4.1 (f79e8e7e4), Pigeonhole version 0.5.4 LMTP as local delivery agent. Erik

Not sure if this is an issue, but Nabble seems to have stopped archiving this newsgroup around 22 Jun. http://dovecot.2317879.n4.nabble.com/ Thought I should probably tell someone P.

Dovecot silently discards duplicates?
by dovecot＠ptld.com 09 Jul '21

09 Jul '21

I setup an alias(a)example.com in postfix to point at me(a)example.com I send one email to me(a)example.com and alias(a)example.com, tried both ways of using CC and putting both addresses in the To field. I see in postfix logs that it delivers two messages to dovecot-lmtp. However i only get one copy of the email in my inbox. I assume dovecot is detecting duplicate emails going to the same location and just discarding one of them. Is there a setting to control this behavior? Can dovecot be told to deliver what it was given and not decide to discard?

Deleting an active sieve script leaves sieve unfunctional
by Tobias Leupold 07 Jul '21

07 Jul '21

Dear devs, I noticed this using Dovecot 2.3.7.2, set up on a newly created Ubuntu 20.04 server. If I delete a sieve script via KMail's managesieve interface, and the script is active, it leaves sieve unfunctional afterwards. What's happening is this: Dovecot creates a USER.sieve script containing all active scripts, e. g.: require ["include"]; include :personal "some-script"; include :personal "some-other-script"; Now if I delete "some-script", it's actually deleted, but USER.sieve is not updated (and still contains 'include :personal "some-script";'). So next time an email is filtered, this happens: mail log: Jul 5 15:20:01 server dovecot: lda(user@domain)<123456> <xxxxxxxxxxxxxxxxxxxxxx>: sieve: Failed to compile script `/srv/sieve/user(a)domain/active-script.sieve' (view user logfile `/srv/sieve/user(a)domain/active-script.sieve.log' for more information) active-script.sieve.log: sieve: info: started log at Jul 05 14:57:54. USER: line 12: error: included personal script 'some_script' does not exist. USER: error: validation failed. So, to avoid this, one has to FIRST deactivate the respectice script, so that USER.sieve is updated and THEN delete the script. Or to manually fix USER.sieve on the server, which is surely not what's intended. So the question is now: Is this a KMail bug, a Doveceot bug, or is the server misconfigured?! Thanks for all help! Cheers, Tobias
