Dovecot proxying to some backend using LOGIN proxy_mech
by Sébastien Riccio 06 Oct '19

06 Oct '19

Hello list, I am currently testing a setup for a PoC wit this configuration. - 1 x Frontend dovecot for proxying IMAP/POP3/LMTP/ManageSieve/Submission - 2 x Backend dovecot with local mail storage The frontend does the user authentification and communicate with the backends using a master password The fronted accepts PLAIN and LOGIN auth mechanisms and talk with backends using PLAIN auth mechanism (with the master password). This works very well, it's cool. Then, I've added to this setup an existing mail server (running another mailserver software) as a 3rd backend, and would like the frontend to also proxy for this, but this time not using master password. This is working for IMAP/POP3 when it uses PLAIN auth, but not for Submission. The backend server in this case only accepts LOGIN auth and not PLAIN on port 587. So I found out there is a field in the passdb we can add (proxy_mech), and I've set it to LOGIN. The frontend seems to now use LOGIN auth mech to talk to this 3rd backend, but the authentication still fails. According to the backend logs, tt seems dovecot proxy is now using LOGIN auth, but sends garbage as username and/or password. Also IMAP that was working when using PLAIN doesn't work anymore with LOGIN. Might this be a bug or this setup shouldn't be supported at all ?

imapsieve administrator scripts are not executed in the order they are defined
by frankagainstthemachine＠gmx.de 06 Oct '19

06 Oct '19

Dear dovecot developers, I have an issue with the Pigeonhole IMAPSieve Plugin and the order in which administrator scripts are executed. Although I cannot find anything about the order in which the scripts are executed, I would expect they are executed in the order they are defined: the one defined by imapsieve_mailbox1_* before the one defined by imapsieve_mailbox2_* in case both match. I defined several administrator scripts; among them one that should be executed when copying a mail to mailbox "Inbox", and one that should be executed when copying a mail from a mailbox "*.Spam" to any other mailbox. No matter in which order I define the two scripts, the one related to "Inbox" is always executed first when I move a mail from "blah.Spam" to "Inbox", see the snipped from my logs below. I guess there might be a bug in file imap-sieve-storage.c, function imap_sieve_mailbox_rules_match(...): The comment in this function states "Insert sorted by rule index", but in case the index of the rule to be inserted is higher than any index already in the "rules" array, the rule is inserted in position 0 instead of being appended to the end, because "insert_idx" is initialized with 0. Since the rule for "*.Spam" is a pattern rule, it is the first rule to be inserted into "rules" (in imap_sieve_mailbox_rules_match_patterns(...)). Afterwards the rule for "Inbox" is always inserted at position 0 (in imap_sieve_mailbox_rules_match(...)), no matter if its rule index is higher or lower than the index of the other rule. The following change could fix this: - unsigned int insert_idx = 0; + unsigned int insert_idx = array_count(rules); Best regards, Frank ----- log ----- [...] Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: mailbox INBOX: MOVE event Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: Pigeonhole version 0.5.7.2 (7372921a) initializing Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.5.7.2 (7372921a) loaded Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Static mailbox rule [1]: mailbox=`*.Spam' from=`*' causes=(COPY) => before=`file:/usr/lib/dovecot/sieve/spamassassin-learn- spam.sieve' after=(none) Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`*.Spam' causes=(COPY) => before=`file:/usr/lib/dovecot/sieve/spamassassin-learn- ham.sieve' after=(none) Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Static mailbox rule [3]: mailbox=`INBOX' from=`*' causes=(COPY APPEND) => before=`file:~/.dovecot.sieve' after=(none) Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Matched static mailbox rule [2] Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Matched static mailbox rule [3] Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: file storage: Using Sieve script path: /var/spool/mail/ user/.dovecot.sieve Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: file script: Opened script `.dovecot' from `/var/spool/mail/ user/.dovecot.sieve' Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: file storage: Using Sieve script path: /usr/lib/dovecot/sieve/ spamassassin-learn-ham.sieve Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: file script: Opened script `spamassassin-learn-ham' from `/usr/ lib/dovecot/sieve/spamassassin-learn-ham.sieve' Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: Opening script 1 of 2 from `/var/spool/mail/user/.dovecot.sieve' Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: Loading script /var/spool/mail/user/.dovecot.sieve [...] ----- dovecot -n ----- #

Is it possible to create and use some lookup table to replace (for instance) %u in mail_location?
by Gerben Wierda 06 Oct '19

06 Oct '19

Suppose my mail_location is: mail_location = maildir:/private/var/mail/nl.rna.mail/%u But I would like to use a simple lookup table to replace %u with another value, say '8DB4E345-9144-4F92-8C9F-9D47BB61CBF8’ instead of ‘username’. Is there a (simple) way to do this?

Home Directory Creation
by Asai 06 Oct '19

06 Oct '19

Hello, I hate to have to ask this, but... why isn't the home directory being created automatically? Due to legacy compatibility we've had to use this type of home dir config: mail_location = maildir:/vmail/%d/%n mail_home = /vmail/%d/%n/home We're in the middle of upgrading to new hardware, and so I'm migrating configs to the new server, Dovecot 2.3.7 and Postfix 3.4.6 On our old server (Dovecot 2.2, Postfix 2.11) the home directory gets created automatically with a new user, but not on this one. The Dovecot debug logs just say "home dir not found." Can anyone point me in the right direction? Thank you, Asai

UNSEEN flag issues with multiple clients
by John Stoffel 04 Oct '19

04 Oct '19

Hi all, I've been bugged by this issue for a while, and while I see that the \UNSEEN flag is specified in the RFC to be reset once *any* client connects and looks at a mailbox, I was wondering if there's a way to change the behavior so that it's tracked on a per-client basis? Or if there's even some way to turn it off so that both my iPhone mail client and my main emacs viewmail mail client don't stomp over each other when looking at my mail folder counts of unread messages. My mail server is running Debian 9.11, which has dovecot 2.2.27-3+deb9u5 as the version. I'm only running IMAP, no POP at all. Thanks, John

Dovecote IMAPSieve user scripts
by Alexander Mankuta 03 Oct '19

03 Oct '19

Hello, I wonder how to configure IMAPSieve with user scripts. I can't find much information on the internet. I have Sieve and IMAPSieve for spam configured as described in the wiki and it works. Documentation mentions that imapsieve_url has to be set to appropriate ManageSieve server but no further explanation is given. What I want to achieve: let users create their own sieve scripts and execute them each time a message is being moved/copied between their mailboxes. I saw mentions of "association of user scripts with mailboxes" but I'm not sure what that means or if it's supported by Thuderbird Sieve extension (or any other software out there). Please advice. -- Regards, Alex

sieve cli
by Matthew Broadhead 03 Oct '19

03 Oct '19

i am using dovecot-2.2.36-3.el7_7.1.x86_64 on centos 7 is it possible to activate / deactivate a sieve script for a mailbox from the command line? my mailboxes are currently stores in /../vmail/domain.tld/username if i activate / deactivate a filter set using roundcube (webmail system) then it creates or deletes a symbolic link /../vmail/domain.tld/username/dovecot.sieve which points to a file /../vmail/domain.tld/username/sieve/managesieve.sieve. if i create this symbolic link manually it doesn't seem to work

Tool to give information about IP's that logged into the accounts
by Jorge Bastos 03 Oct '19

03 Oct '19

Howdy, I'm looking for a tool that can give me the information about the IP's that have logged in the accounts, for history purpose. Is there something that can grab the logs and create a database and give me this information in some nice web interface or so? Thanks in advanced, Jorge,
