dovecot 3.16 replicator Problem?
by Günther J. Niederwimmer 20 Aug '21

20 Aug '21

Hello list, I have a problem with the replicator (config) I mean it doesn't work anymore since version 3.16? How can you turn up the log level with this tool? I think the full sync is still possible to some extent. I deleted a test user who was restored after a day. Question: has something changed in the config so that the whole thing works again Thanks for a answer, -- mit freundlichen Grüßen / best regards Günther J. Niederwimmer

ssl_params error on RHEL7 FIPS enabled
by Brad Partin 19 Aug '21

19 Aug '21

All, The machine I’m running dovecot on is: RHEL7.9 3.10.0-1160.31.1.el7.x86_64 I can run Systemctl restart dovecot then status or /usr/libexec/dovecot/ssl-params and I get the following error. Info: Generating SSL parameters Fatal: ssl_iostream_generate_params(4096) failed: DH_generate_parameters(bits=512, gen=2) failed: error:0506A06E:lib(5):func(106):reason(110), error 0506A003:lib(5):func(106):reason(3) Error: child process failed with status 22784 I can generate a diffie-hellman pem with openssl dhparam -out /etc/dovecot/dh.pem 4096 But dovecot 2.2.36 does not have the option of telling it where the dh.pem file is located in the config like version 2.3 does. Is my error related to FIPS and is there a way around it? My dovecot version is: Dovecot version 2.2.36 release 8.el7 Thanks in advance to anyone willing to help out, I know it’s voluntary 🙏 Thanks, bpartin2009 Sent from my iPhone

Odd config problem in Debian Bullseye / dovecot 2.3.13
by Perry E. Metzger 19 Aug '21

19 Aug '21

Hi all! For a long time, I've been running this out of cron as user "perry": /usr/bin/doveadm expunge -u perry mailbox SPAM not seen before 7d After upgrading to 2.3.13 as a result of a debian upgrade, this broke. I now am suddenly getting: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 132: ssl_key: Can't open file /etc/ssl/private/ssl-cert-snakeoil.key: Permission denied Attempting things like setting "-o ssl_key=/dev/null" and the like don't work. I could of course run this as root but I'd strongly prefer not to. Anyone have any ideas? Perry

Snarf plugin retirement
by Brent Busby 19 Aug '21

19 Aug '21

I wondered if it's possible to get the Snarf plugin back, if not in the official Dovecot distribution, then at least to somehow build the plugin source on a modern release...because: Though the documented purpose for Snarf was to ease migration off of UW-IMAP, that's not the only thing it was useful for. Unfortunately, every mailreader that I've seen that can run within Emacs -- and I've tried Gnus, VM, and RMAIL -- all _require_ the use of a ~/mbox file when pulling from a local mail spool on the same machine. (This does not affect IMAP usage of those mailreaders, only local file access.) Non-Emacs mailreaders like Alpine and Mutt have sufficiently robust file-locking safety that they can work on the local mail spool in /var/spool/mail or /var/mail or what have you directly without copying your mail somewhere else first, so for Alpine and Mutt, use of ~/mbox is possible but not necessary. But it seems that for every mailreader that does run within Emacs, if the mail source is local rather than IMAP, there is no other way to operate the program than to have it copy your mail from the spool to ~/mbox. On a system where there are users who sometimes work that way, doing local mail access in Emacs, and other times use IMAP via Dovecot, you have a mess without the Snarf plugin. I realize this is a peculiar situation, so I don't expect Snarf to necessarily be put back into Dovecot. I was wondering how it might be possible to build it today though...for any out there who may use Emacs for mail most of the time...but occasionally also want Dovecot IMAP on the same machine where they're normally using an ~/mbox file for Emacs' sake. UW-IMAP may be dead...but long live GNU Emacs! -- + Brent A.

BUG REPORT: MAIL-CRYPT plugin: doveadm mailbox cryptokey -O option
by ean365 17 Aug '21

17 Aug '21

Aki: I have identified a bug in the "*-O*" option of "*doveadm mailbox cryptokey password*" plugin command -- it is expecting an argument, but it is supposed to be a boolean option. I have also identified the (simple) fix to the source on github... /I am a dovecot community noob, so please forgive me if this has already been identified... (if so, I hope it gets fixed soon)... / The "-O" option in *struct doveadm_cmd_mcp_key_password* is set to expect a *STR* parameter, but it should be *BOOL*. See line 1027 in plugins/mail-crypt/doveadm-mail-crypt.c of master branch... Currently: ***DOVEADM_CMD_PARAM**(**'O'**, **"ask-old-password"**, CMD_PARAM_STR, **0**) *Should be: ***DOVEADM_CMD_PARAM**(**'O'**, **"ask-old-password"**, CMD_PARAM_BOOL, **0**)* Workaround is to specify *-O* last on command line with a dummy argument, like this: *doveadm mailbox cryptokey password -N -O ""* Also, a quick question and suggestion -- Why does the *doveadm mailbox cryptokey password* command not ask for a new password twice, with a check that both entries must match before the password is changed? The last thing we would want is to type something wrong accidentally, and change the new password to something unknown -- rendering encrypted email unrecoverable. I would like to suggest that the code in *cmd_mcp_key_password_run* be amended to include verifying password entry twice. (I am writing a simple addition to postfixadmin that changes the user's mail-crypt password whenever they use postfixadmin to change their login password. It calls *doveadm* to change the keys. I came across this bug while working through this.) Thanks for all your help! Eric **

SSL TLS SNI error certificate is empty
by silvan＠datavenia.nl 16 Aug '21

16 Aug '21

Hello, I’ve tried implementing TLS SNI for my Postfix/Dovecot setup. I have it working in Postfix, but this example for Dovecot: https://doc.dovecot.org/configuration_manual/dovecot_ssl_configuration/#wit… doesn’t seem to work for me. I’m using LetsEncrypt certificates. They work without a problem with the regular ssl_cert and ssl_key settings like this: ssl_cert = </docker/rancher-active-proxy/letsencrypt/live/datavenia.nl/fullchain.pem ssl_key = </docker/rancher-active-proxy/letsencrypt/live/datavenia.nl/privkey.pem … but as soon as I put them in local_name blocks like this: local_name datavenia.nl { ssl_cert = </docker/rancher-active-proxy/letsencrypt/live/datavenia.nl/fullchain.pem ssl_key = </docker/rancher-active-proxy/letsencrypt/live/datavenia.nl/privkey.pem } local_name verovia.nl { ssl_cert = </docker/rancher-active-proxy/letsencrypt/live/verovia.nl/fullchain.pem ssl_key = </docker/rancher-active-proxy/letsencrypt/live/verovia.nl/privkey.pem } and restart dovecot I get the following error: dovecot: imap-login: Error: Failed to initialize SSL server context: Can't load SSL certificate (ssl_cert setting): The certificate is empty: user=<>, rip=213.127.63.224, lip=142.93.135.7, session=<wKjTIaLJtSXVfz/g> I have verified that the certificate paths are correct, the files have content. I’ve already checked permissions (chmodded 777 to debug), as well as the that these are actually symlinks (updated the config to point to the real files) but nothing so far seems to change anything. I have also recreated my dh.pem (4096). I’m hoping anyone has any idea where I might be going wrong.

auth-worker looses MySQL connection and doesn't reconnect when MySQL/MariaDB has been restarted
by Christian Ruppert 16 Aug '21

16 Aug '21

Hey, I have MariaDB 10.5.10 and Dovecot 2.3.14.1 right now but it's broken since a few months already. I don't remember when it started and what versions I had running of both. As stated in the subject, the Dovecot auth-worker looses connection during a MySQL/MariaDB restart, which is ok so far, but it doesn't reconnect for some reason and instead all further actions fail because of it, like doveadm or IMAP login / commands etc. Aug 15 13:21:28 thor dovecot[20862]: auth-worker(24450): Warning: sqlpool(mysql): Query failed, retrying: Connection was killed Aug 15 13:21:28 thor dovecot[20862]: auth-worker(24450): Error: conn unix:auth-worker (pid=24449,uid=97): auth-worker<376>: sql(user@example.com,::1,<somesession>): Password query failed: Connection was killed Aug 15 13:21:30 thor dovecot[20862]: imap-login: Disconnected (auth service reported temporary failure): user=<user(a)example.com>, method=PLAIN, rip=::1, lip=::1, secured, session=<somesession> This repeats basically for every command / action I do until I restart dovecot or kill the auth-worker process. Both works. dovecot-sql.conf.ext: driver = mysql connect = host=/run/mysqld/mysqld.sock dbname=mail user=dovecot password=SOMEPW Steps to reproduce: Use MySQL in Dovecot Restart MySQL while Dovecot is running Do either some doveadm commands or try to login e.g. using IMAP or just try to navigate through your mailbox See errors / logs pkill -f 'dovecot/auth worker' Try doveadm etc. again Works -- Regards, Christian Ruppert

i_stream_read_memarea: assertion failed: (!stream->blocking)
by Stuart Henderson 16 Aug '21

Continuation of https://dovecot.org/pipermail/dovecot/2021-January/121235.html - I didn't get a reply to my last mail, so ended up deleting the various messages (or in some cases mailboxes) and stopped running into problems for a while, but am now seeing it again. I get "i_stream_read_memarea: assertion failed: (!stream->blocking)" when accessing some messages. Backtrace and doveconf -n below. $ doveadm -D search from abcdefghij [...] Aug 13 17:30:02 doveadm(sthen): Debug: Mailbox trash: UID 1177: Looked up field guid from mail cache Aug 13 17:30:02 doveadm(sthen): Debug: Mailbox trash: UID 1177: Opened mail because: 1/1 headers not cached (first=from) (Mail has other cached fields, reset_id=1470764070) Aug 13 17:30:02 doveadm(sthen): Debug: Mailbox trash: UID 1178: Looked up field guid from mail cache Aug 13 17:30:02 doveadm(sthen): Debug: Mailbox trash: UID 1178: Looked up field guid from mail cache Aug 13 17:30:02 doveadm(sthen): Debug: Mailbox trash: UID 1178: Looked up field guid from mail cache Aug 13 17:30:02 doveadm(sthen): Debug: Mailbox trash: UID 1178: Opened mail because: 1/1 headers not cached (first=from) (Mail has other cached fields, reset_id=1470764070) Aug 13 17:30:02 doveadm(sthen): Panic: file istream.c: line 345 (i_stream_read_memarea): assertion failed: (!stream->blocking) Abort trap (core dumped) Some other searches hitting the same message do succeed though e.g. "doveadm search mailbox trash".

The messages where I'm seeing this so far seem to all be stored with lz4 (a couple of years old mostly). Any ideas? GNU gdb (GDB) 7.12.1 Copyright (C) 2017 Free Software Foundation, Inc.

Enabling autoexpunge for mailboxes created by sieve rules
by Salatiel Filho 16 Aug '21

16 Aug '21

Hi everyone. I have global sieve rules that can create mailboxes automatically by using "fileinto :create some/mailbox/that/does/not/exist". The emails are delivered to dovecot using lmtp and I can see the mailboxes created just fine. Is there a way to configure all new mailboxes created by those sieve rules to automatically set to autoexpunge after 15 days ? I tried this , but it did not work. namespace { type = public separator = / prefix = mypublic/ location = maildir:/var/spool/vmail/dovecot/mail/ subscriptions = no list = children mailbox * { autoexpunge=15d } } plugin { acl = vfile } # dovecot --version 2.3.15 (0503334ab1) Thanks!
