Something obvious in my sieve?
by ＠lbutlr 19 Aug '21

19 Aug '21

I get the following error for this: line 24 is the "contains subset" line .active_sieve: line 24: error: expecting test identifier after ',' in test list, but found '('. .active_sieve: line 24: error: expecting ',' or end of test list ')', but found '{'. .active_sieve: error: parse failed. if anyof (body :contains "files transferred: 0", (header :contains "subject" "a specific subject goes here" ) { This clause produces no error if anyof (header :contains "from" "@unwanted", envelope :matches :detail "to" "extension", exists "X-Facebook" ){ What am I missing? -- "Are you pondering what I'm pondering?" "Yes Brain, but if our knees bent the other way, how would we ride a bicycle?"

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 18 Aug '21

18 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

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". Somehow after various other searches trying to figure out what triggered the crash and what didn't (e.g. "doveadm -D search mailbox trash uid 1170:12000 from abc" crashed but "uid 1170:1190" didn't) it has stopped failing with that particular message, but I am still hitting it in at least one other mailbox. 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!

Why do so many dovecot list mails fail dmarc?
by dovecot＠ptld.com 16 Aug '21

Im trying to get my head around this problem that too many valid emails from the mailing list fail dmarc. Why when other mailing list don't seem to have the same problem? I see today it says "signature verification failed", but why? Is there a problem with protonmail's dkim key? Is the dovecot list altering the message body? Is something wrong on my server's end? The example today was an email from @protonmail.ch, and the headers were: Return-Path: <dovecot-bounces(a)dovecot.org> Delivered-To: dovecot(a)ptld.com Received: from smtp.ptld.com by host.ptld.com with LMTP id +SjBLQqiFmFSbgIAjbxwTg (envelope-from <dovecot-bounces(a)dovecot.org>) for <dovecot(a)ptld.com>;

Help to setup a Unix socket based authentication server for dovecot in Python
by Sherin A 15 Aug '21

15 Aug '21

Hi, I am building a custom server platform in which dovecot is used for imap/pop . But the default authentication mechanism is not suitable for me becuase each domain will have different system users and different location for mail storage . So I need to create a custom authentication mechanism using python . There is an option to use Key-value authentication (dict) database via socket as per https://doc.dovecot.org/configuration_manual/authentication/dict/#complete-… The above documentation link have a sample perl script too to send authentication to uri = proxy:/var/run/auth_proxy_dovecot/socket:somewhere So my question is how the inputs are send to the socket file ? in which format ? How the result return ? and in which format ? Let us say I can create a python socket program that can listen to /var/run/auth_proxy_dovecot/socket for getting the inputs from dovecot , but what is the format Is it like the following AUTH PLAIN USER test(a)myemail.com PASS mypassword I looked into the documentation and developer documentation, I am unable to see how dovecot send the data , I can see a sample perl for answering dict lookups. Any one have a python alternative for it. ? -- *Sherin Abdulkhareem* Chairman & Managing Director email Email sherin(a)sherin.in <mailto:sherin@sherin.in> mobile Mobile (+91)9496533234 office Office (+91)4716007799 *Syslint Technologies India Private Limited* First Floor,Asiatic Business Center Kazhakkootam, Trivandrum PIN-695582 India Facebook <https://facebook.com/sherin.co.in> LinkedIn <https://linkedin.com/in/sherina> Google+ <https://plus.google.com/+sherinAbdulkhareem> sherin.in <http://sherin.in>
