How are imap images supposed to be stored
by d.gentner＠m4ever.de 04 Sep '19

04 Sep '19

Hello. This is a question about the imap protocol, since I am having a hard time finding these things out, so I hope you guys can help me. We are using Dovecot to receive mails and having an issue with Thunderbird. Basically, we are running into this bug with a lot of people: https://bugzilla.mozilla.org/show_bug.cgi?id=216308. <https://bugzilla.mozilla.org/show_bug.cgi?id=216308> The gist of it is, that sometimes, when there is an image linked with the imap:// protocol in the … [View More]

Mailcrypt plugin private password
by info＠unkn0wn3d.com 04 Sep '19

04 Sep '19

Hello there, is there a way to make the mailcrypt plugin use the user's password or at least store it in a hashed value? I'm using a passwd file for authentication. I feel uncomfortable saving the private password in plaintext in that file. Regards

Dovecot and Apple's Mail.app not playing nicely?
by Coy Hile 03 Sep '19

03 Sep '19

Hi all, Is there anything cute one has to take into account when using Dovecot with users of Apple’s Mail.app? Behavior I’m seeing is that if I delete or move messages via Webmail (Roundcube, Horde, or even ActiveSync via Mail.app on my phone), they do get moved or deleted. However, if I take the same actions in the desktop mail client, when logging in to the Webmail (or phone) app, I see the messages still seeming to be in the Inbox. Is this known behavior? A peculiarity in Apple Mail? --… [View More]

Re: Re: Quota count and clone questions
by Bratislav ILIC 03 Sep '19

03 Sep '19

Hi, I presume you figured this out after all this time, but in any case. Since quota_clone is not cumulative, it always inserts new record with actual quota, to be able to get correct results in postfixadmin one must: DROP TRIGGER mergequota2 ON quota2; And to prevent ERROR: duplicate key value violates unique constraint "quota2_pkey": CREATE FUNCTION public.clone_quota2() RETURNS trigger LANGUAGE plpgsql AS $$ BEGIN UPDATE quota2 SET bytes = NEW.bytes, … [View More] messages = NEW.messages WHERE username = NEW.username; IF found THEN RETURN NULL; ELSE RETURN NEW; END IF; END; $$; And then: CREATE TRIGGER clonequota2 BEFORE INSERT ON quota2 FOR EACH ROW EXECUTE PROCEDURE public.clone_quota2() ; And finally just put: quota_clone_dict = proxy::sqlquota Hope this helps somebody trying to figure out this too. > I figured out that I can't just drop maintaining quota2 if I want > postfixadmin to report the quota status. > > I also figured out a way to run a test on my config guesses.

LMTP Post login script for acl_groups
by lists＠mlserv.org 03 Sep '19

03 Sep '19

Hi, I use a post login script for imap, to fetch acl groups from LDAP. Because Dovecot can only deal with a single value, which must be a comma seperated list of groups, I decided to use a post login script do deal with multi values in LDAP: This looks like this in LDAP: rnsMSACLGroup: admin rnsMSACLGroup: automx rnsMSACLGroup: amavis rnsMSACLGroup: postfix rnsMSACLGroup: dovecot rnsMSACLGroup: rspamd rnsMSACLGroup: powerdns rnsMSACLGroup: sogo rnsMSACLGroup: zabbix rnsMSACLGroup: dane-users … [View More]rnsMSACLGroup: gentoo rnsMSACLGroup: openbsd My post login script looks like this: --------------------------------------------------------- #!/bin/sh BINDDN='cn=dovecot-postlogin,ou=people,ou=it,dc=roessner-net,dc=de' BINDPWFILE='/etc/dovecot/ldap-postlogin.secret' BASE='ou=people,ou=it,dc=roessner-net,dc=de' LDAPSEARCH="/usr/bin/ldapsearch" AWK="/usr/bin/awk" test -x ${LDAPSEARCH} || exec "$@" test -x ${AWK} || exec "$@" ACL_GROUPS=$( ${LDAPSEARCH} -LLL -ZZ -y ${BINDPWFILE} -xD ${BINDDN} -b ${BASE} "(rnsMSDovecotUser=${USER})" rnsMSACLGroup | \ grep rnsMSACLGroup | \ ${AWK} -vORS=, '{ print $2 }' | \ sed 's/,$/\n/' ) export ACL_GROUPS export USERDB_KEYS="${USERDB_KEYS} acl_groups" exec "$@" --------------------------------------------------------- This script is included in imap-postlogin executables and works for logged in users. But it does not work for LMTP. LMTP itself seems not to have any permissions to access the folders associated with these groups. I thought, I simply could add the imap-postlogin block to lmtp-postlogin and that would work, but it doesn't. So here is the question: What am I missing in Dovecot that LMTP can also have ACL_GROUPS like the imap service? Here is my config (non-defaults): --------------------------------------------------------- doveconf -n # 2.3.7.1 (0152c8b10): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.1 (db5c74be) # OS:

flags not synced correctly with dovecot sync (dsync)
by Dan Christensen 31 Aug '19

31 Aug '19

I'm running dovecot 2.3.4.1 from https://repo.dovecot.org/ on Ubuntu 18.04 on three machines that I'll call server, laptop1 and laptop2. Both laptop1 and laptop2 run dovecot sync against server to keep local copies of my imap folders. Even when I initially had only two machines, laptop1 and server, I occasionally noticed that flags were lost, usually custom flags used by Gnus, but I couldn't reliably reproduce the problem. Now that I have two laptops syncing against the server, the problem … [View More]has gotten worse and I figured out a way to reproduce it: - on server: create new IMAP folder test, and put two read messages in it - on laptop1: doveadm sync -u user -l 10 -m test -f user@server - on laptop2: doveadm sync -u user -l 10 -m test -f user@server At this point, all three machines show the two messages M1 and M2 as being read. - on laptop1: mark message M1 unread - on laptop2: mark message M2 unread - on laptop1: doveadm sync -u user -l 10 -m test -f user@server Both laptop1 and server have M1 unread, M2 read, as expected. - on laptop2: doveadm sync -u user -l 10 -m test -f user@server Now laptop2 and server have M1 *read*, M2 unread. - on laptop1: doveadm sync -u user -l 10 -m test -f user@server Now laptop1 and the server have both M1 and M2 *read*. - on laptop2: doveadm sync -u user -l 10 -m test -f user@server Now laptop2 has both read as well. The two lines that say "*read*" are wrong in my opinion. dsync propagated a read mark to an unread message, even though that message was marked unread more recently than it was marked read. I usually use stateful sync, and get many related problems. I just did a test in which M1 and M2 started out read, and I started with empty files named dstate.test on laptop1 and laptop2. Then I did the above procedure, using the command doveadm sync -u user -l 10 -m test -s "`cat dstate.test`" user@server > dstate.test At the end, laptop2 and server had both messages unread (which is good), but laptop1 had only M1 unread, and repeated runs of the sync command did not correct this. So the stateful sync failed to detect a change. Are these bugs in dovecot? Is there more information that I can provide? The output of doveconf -n on one machine is below, and the others are almost identical. Thanks for any help!

doveadm backup mdbox - initial copy slow
by Gerald Galster 30 Aug '19

30 Aug '19

Hello, when calling doveadm backup like in the following example, it seems to flush every email to disk maxing out harddrives (iops) and resulting in very poor performance: Calling doveadm -o plugin/quota= backup -u "statusmails(a)domain.com" "mdbox:/backup/vmail/domain.com/statusmails" finished in 212 secs [changes:1800 copy:1800 delete:0 expunge:0] The source mdbox holds 1800 small emails and uses about 20 MB disk space only. I've tried -f (full sync) and -l 30 (locking the mailbox) which … [View More]

User / Pass SQL queries
by Michael Hallager 29 Aug '19

Hi all, Is there any reason Dovecot shows the 'user' variable (ie: user(a)domain.tld) being obtained in the password query and not the (more logical) user query? Thanks, Michael

Feature wishlist: Allow to hide client IP/host in submission service
by Sebastian Krause 28 Aug '19

28 Aug '19

Hi, In many mail setups a required feature (for privacy reasons) is to hide the host and IP of clients (in the "Received" header) that use the authenticated submission over port 587. In Postfix that's possible (https://serverfault.com/q/413533/86332) but not very nice to configure especially if you only want want to strip the Received header for port 587 submissions, but not on port 25. As far as I can see this configuration is not possible at all in the Dovecot submission server because the … [View More]
