ot: how to t/s TBird problems ?

I have a Dovecot/Postfix/MariaDB on a Centos, just have a user ask me: ------------------ I recently upgraded my Thunderbird email client and have experienced problems since. It appears that when Tbird polls for new messages it gets held up waiting for a response from the server I'm using POP port 995. Any ideas as to why I'm having a problem ? ------------------- how to investigate such issue ? CentOS release 6.10 (Final) # dovecot --version 2.3.11.3 (502c39af9) load average on server 0.05/0.01 user log shows like: Oct 12 10:08:50 pop3-login: Info: Login: user=<user(a)tld.com.au>, method=PLAIN, rip=49.111.222.333, lip=103.xxx.yyy.zzz, mpid=17371, TLS, session=<E83xW8rqDPkxw3EW> Oct 12 10:09:34 pop3(user(a)tld.com.au)<17371><E83xW8rqDPkxw3EW>: Info: Disconnected: Logged out top=0/0, retr=0/0, del=0/114194, size=10616009472 Oct 12 10:14:36 imap-login: Info: Login: user=<user(a)tld.com.au>, method=PLAIN, rip=49.111.222.333, lip=103.xxx.yyy.zzz, mpid=17460, TLS, session=<ftiLcMrqR/gxw3EW> Oct 12 10:14:37 imap(user(a)tld.com.au)<17460><ftiLcMrqR/gxw3EW>: Info: Logged out in=152 out=69724 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=1 body_bytes=68628 Oct 12 10:28:27 pop3-login: Info: Login: user=<user(a)tld.com.au>, method=PLAIN, rip=49.111.222.333, lip=103.xxx.yyy.zzz, mpid=17714, TLS, session=<+WsXosrqK/gxw3EW> Oct 12 10:29:16 pop3(user(a)tld.com.au)<17714><+WsXosrqK/gxw3EW>: Info: Disconnected: Logged out top=0/0, retr=1/76174, del=0/114195, size=10616085600 Oct 12 10:32:19 imap-login: Info: Login: user=<user(a)tld.com.au>, method=PLAIN, rip=49.111.222.333, lip=103.xxx.yyy.zzz, mpid=17817, TLS, session=<bZftr8rqq/gxw3EW> Oct 12 10:32:20 imap(user(a)tld.com.au)<17817><bZftr8rqq/gxw3EW>: Info: Logged out in=153 out=135592 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=1 body_bytes=134503 Oct 12 10:45:58 imap-login: Info: Login: user=<user(a)tld.com.au>, method=PLAIN, rip=49.111.222.333, lip=103.xxx.yyy.zzz, mpid=18081, TLS, session=<U3674Mrqzfgxw3EW> Oct 12 10:45:59 imap(user(a)tld.com.au)<18081><U3674Mrqzfgxw3EW>: Info: Logged out in=152 out=24602 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=1 body_bytes=23514 Oct 12 10:48:49 pop3-login: Info: Login: user=<user(a)tld.com.au>, method=PLAIN, rip=49.111.222.333, lip=103.xxx.yyy.zzz, mpid=18135, TLS, session=<y1/r6srqtPsxw3EW> Oct 12 10:49:53 pop3(user(a)tld.com.au)<18135><y1/r6srqtPsxw3EW>: Info: Disconnected: Logged out top=0/0, retr=2/166190, del=0/114197, size=10616251743 Oct 12 10:50:42 imap(user(a)tld.com.au)<3274><cr10yqTqifgxw3EW>: Info: Logged out in=192516 out=5957294 deleted=0 expunged=0 trashed=0 hdr_count=263 hdr_bytes=358656 body_count=126 body_bytes=5110403 Oct 12 10:50:42 imap(user(a)tld.com.au)<3271><hLl0yqTqh/gxw3EW>: Info: Logged out in=78324 out=58677 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 Voytek

2.3.14: stale imap-login processes due to bogus user setup tying up process limit
by Volker Stolz 16 Dec '22

16 Dec '22

I just dealt with an interesting Dovecot issue on our small server, and thought I might share it. I also feel that although in the end it was a configuration error, Dovecot should somehow avoid leaving this processes around and hence filling up the process limit quickly. - set up Dovecot IMAP on Debian buster (either with the older 2.3.x Debian package, or 2.3.14 from the dovecot-repo) - config: ... namespace inbox { inbox = yes location = ... default settings ... ... passdb { args = scheme=HMAC-MD5 username_format=%u /etc/dovecot/users driver = passwd-file } protocols = " imap" ... userdb { args = blocking=no driver = passwd } ... - secret sauce: have a user in the passdb that doesn't have a physical account on the system yet (we were migrating to a new machine). The log-file shows successful authentication for that user (after we flipped DNS to point to this new machine), but over time (2-3 times/day) we were left with an increasing number of `imap-login` processes in state `pre-login`, eventually requiring a dovecot restart. Dialling up process_limits didn't seem to help, we'd just get more of these stale processes. After creating the user on the system, the behaviour reverted to normal, no more stale processes. I do not know what error message that user received on their end, but since we announced we were migrating, they probably just ignored it and thought it as part of the transition. Best, Volker (a happy & long Dovecot user)

access dict in lua auth script
by Tobias Florek 08 Dec '22

08 Dec '22

Hi! I want to access a configured dictionary in a lua authentication script. Unfortunately the documentation <https://doc.dovecot.org/admin_manual/lua/> does mention a dict object but no way to get one. I also did not find any lua tests in dovecot's source code. Is using the built-in dict not supported? Cheers, Tobias Florek

moving messages between namespaces go into purge
by Marc 07 Dec '22

07 Dec '22

I think it would be nice to have an option where the moving of messages between namespaces (by automated server scripts) would not result in messages ending up in the 'purge' queue. Currently when you move these copied messages, they end up in the purge queue combined with messages that users deleted. I am more or less forced to purge the mailbox after moving GB's while I prefer not to do this, because I would like to keep the opportunity to recover from the purge queue. Maybe there is a way to 'deduplicate' this purge queue?

Doveadm Move Query
by Simon B 01 Dec '22

01 Dec '22

I have a production Dovecot problem and although I searched the mailing lists, I could not find an answer and I hope you can give me a quick answer/pointer in the right direction. I have mails for a user (user(a)domain.net) under /var/spool/mail/virtual/ domain.net/user and I want to move ALL the mails to /var/spool/mail/virtual/domain.com/user If I use #doveadm -Dv move -u user(a)domain.net Maildir:/var/spool/mail/virtual/ domain.net/user Maildir:/var/spool/mail/virtual/domain.com/user ALL I get doveadm(root): Fatal: Unknown argument MAILDIR:/var/spool/mail/virtual/ domain.com/user if I use #doveadm -Dv move -u user(a)domain.net Maildir:/var/spool/mail/virtual/ domain.net/user /var/spool/mail/virtual/domain.com/user ALL doveadm(root): Fatal: Unknown argument /var/spool/mail/virtual/ domain.com/user What the hell am I doing wrong!? :) Thanks.

bug: ARGON2 hash selection incompatible with LDAP
by Krisztián Szegi 25 Nov '22

25 Nov '22

Good day to all, this is my first post to the mailing list! I'd like to report that non-binding auth to (Open)LDAP doesn't work if the latter hashes passwords with ARGON2. Although dovecot (I am using http://2.3.19.1) does support ARGON2 with libsodium, but it doesn't recoginize hashes beginning "{ARGON2}$argon2id$" stored (and hashed, using ppolicy module's hashCleartext) by OpenLDAP. Now, I understand that ARGON2I, -D, and -ID are not compatible, but the ACTUAL algorithm is there between the two $. Furthermore, I think dovecot is in the minority here, I haven't met any software that specifies the ARGON2 subtype between {}. BTW, I haven't met any software that hashes passwords with ARGON2, but not with the ARGON2ID subtype (where libsodium is available, which also seems to be the standard here), as THAT is the recommended one anyway. I patched the rpm in OpenSUSE repo to alias {ARGON2} to {ARGON2ID}: https://build.opensuse.org/package/view_file/home:Samonitari:branches:openS… Could we get something like this (but maybe more correct) into the official source? Maybe a config switch to alias it runtime? Thanks for the attention: Krisztián

compiled sieve files svbin ?
by jeremy ardley 23 Nov '22

23 Nov '22

Hi, I have recently started using claws mail to manage my user sieve scripts using server dovecot-sieve_1%3a2.3.13+dfsg1-2_arm64.deb I originally edited ~/.dovecot.sieve to hold my script and I recall that ~/.dovecot.svbin was automatically generated on first use. (either that or I have forgotten that I had used sievec) Later I used claws mail to generate sieve scripts but they were written into directory ~/sieve/ In experimentation I changed ~/.dovecot.sieve into a link to my principal script ~/sieve/main.sieve The oddity now is that sieve seems to be working when there is no compiled version Should I expect a compiled .svbin version to be generated from claws client? Or generated by first run of the sieve server on the user account? Or should I manage the scripts with claws, but log in to the server later to generate the .svbin versions? In any event what effect does not having a .svbin version have on typical small installation? -- Jeremy
