2.3.17: Panic on LMTP deliveries
by Volker 12 Dec '21

Hello! While searching for an explanation for the fact that after updating to Dovecot 2.3.17_1 (FreeBSD 12.2) I suddenly stopped receiving emails and following error messages appeared in the dovecot.log, /Error: lmtp-server: conn unix:uid=125 [1]: rcpt user(a)domain.tld: duplicate db: User user(a)domain.tld doesn't have home dir set, disabling duplicate database// // //Dec 12 08:42:54 lmtp(user(a)domain.tld)<80363><z7AxDf6ntWHrOQEAp6O1gg>: Panic: file imem.c: line 65 (i_strconcat): assertion failed: (str1 != NULL) /I found your answer here <https://www.mail-archive.com/dovecot@dovecot.org/msg84893.html>: /Problem confirmed. This is a 2.3.17 regression. Tracking internally as DOP-2659./ / Regards, Stephan./ But what exactly does your answer mean for those affected? That all users who use Dovecot and use the whole thing without "mail_home" and only with "mail_location", must wait until a BugFix appears to be able to receive emails again? Thanks in advance and have a nice advent sunday Volker P. S.: In my case dovecot -n shows /mail_location = maildir:/var/mail/vhosts/%d/%n// //mail_home = /var/mail/vhosts/%d/%n /so mail_home is even set!/ /

RE: virtual mailbox domains??

Thanks *so much* for all your help. Another complete rebuild and I think I’ve finally got it. I was able to log into mail.sizzelicks.com for smoker1(a)sizzelicks.com <mailto:smoker1@sizzelicks.com> this time with no trouble. I sent an email to smoker1(a)sizzelicks.com <mailto:smoker1@sizzelicks.com> from a gmail account and was able to retrieve it in Thunderbird. I replied to the gmail email and in gmail.com I got the response. Now I can add email accounts to the database for any of our domains and they work! I've added responses below. -----Original Message----- From: owner-postfix-users(a)postfix.org <owner-postfix-users(a)postfix.org> On Behalf Of raf Sent: Thursday, December 9, 2021 1:07 AM To: postfix-users(a)postfix.org Subject: Re: virtual mailbox domains??

The reference to private/auth is referring to dovecot's authentication socket under postfix's chroot directory. It's in /var/spool/postfix/private/auth, not /etc/postfix. You have set that up in dovecot's config: service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } My version of that looks like: service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } So it looks like that should be OK. Does /var/spool/postfix/private/auth exist? Mine has root as owner/group. Yours should have postfix as owner/group. But that shouldn't matter as long as the mode is 0666. I must of changed the mode to 0660 but per your suggestion I changed it to 0666. Thanks. Yes it does exist. ls -l /var/spool/postfix/private/auth srw-rw---- 1 postfix postfix 0 Dec 8 21:50 /var/spool/postfix/private/auth If not, check dovecot's log messages for problems with it. But I don't know what to look for. The dovecot mailing list folks might be more useful for that. It should exist and be used by dovecot. If you have lsof installed, you can check that: > sudo lsof /var/spool/postfix/private/auth COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME dovecot 17341 root 53u unix 0xffff8e43c69f7400 0t0 16873340 /var/spool/postfix/private/auth type=STREAM auth 1521507 dovecot 13u unix 0xffff8e43c69f7400 0t0 16873340 /var/spool/postfix/private/auth type=STREAM auth 1521507 dovecot 21u unix 0xffff8e43c417c800 0t0 69451443 /var/spool/postfix/private/auth type=STREAM auth 1521507 dovecot 22u unix 0xffff8e43c9fc2400 0t0 69453124 /var/spool/postfix/private/auth type=STREAM sudo lsof /var/spool/postfix/private/auth COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME dovecot 4550 root 58u unix 0x0000000000000000 0t0 1305802532 /var/spool/postfix/private/auth type=STREAM Something else that might or might not be a (different) problem is that the TLS certificate at mail.sizzlelicks.com doesn't certify the domain mail.sizzlelicks.com. Its list of domains contains sizzelicks.com and <http://www.sizzelicks.com> www.sizzelicks.com but not mail.sizzelicks.com. That might cause problems with Thunderbird trying to connect for IMAPS. I think you reported such an error message earlier. So you might want to add the mail.sizzelicks.com domain to that certificate. But that's not related to the failure to connect to the dovecot auth socket. You are correct and I sure wish I saw *this* a week ago😊. I did a rebuild due to lots of trouble trying to add the certs. Now I’ve got it all back up with the certificates for all of the mail.mydomain.com MX records.

Force clients to use pgp encryption when sending email?
by Austin Witmer 09 Dec '21

09 Dec '21

Hello all! I am looking for a way to force imap clients to encrypt their messages with the public keys of the recipients before sending them. Would a post-login script in dovecot work for something like this? I am using postfix and dovecot on my mail server. Basically I want the server to check if the message being sent is encrypted with OpenGPG and either proceed or reject the message based on that criteria. If the message is rejected, the user could then encrypt the outgoing email message with the recipient public key and try again. Does anybody have a suggestion on how to implement something like this? Would there be a way that the the client software (thunderbird) could show an alert asking the user to encrypt the message and then attempt to resend the message? I realize that you can tell a client (like thunderbird) to automatically encrypt outgoing messages with pgp but I would like to have some way to enforce that policy at the server level before the email is sent. I want to have all messages end-to-end encrypted, hence my desire for functionality like this. Any suggestions are welcome. Thanks in advance for your help!

No source packages in APT repo?
by Shawn Heisey 08 Dec '21

08 Dec '21

I added a deb-src entry to my APT config matching the deb entry: deb https://repo.dovecot.org/ce-2.3-latest/ubuntu/focal focal main deb-src https://repo.dovecot.org/ce-2.3-latest/ubuntu/focal focal main When this is there, I see a warning when running "apt update". W: Skipping acquire of configured file 'main/source/Sources' as repository 'https://repo.dovecot.org/ce-2.3-latest/ubuntu/focal focal InRelease' does not seem to provide it (sources.list entry misspelt?) Were source packages excluded deliberately? The github repo for dovecot does not have a "debian" directory, which is the other route that would allow me to build packages. Thanks, Shawn

Hello, dovecot --version 2.3.17 (e2aa53df5b) debug log: Debug: duplicate db: transaction: Too many duplicate IDs locked Debug: duplicate db: transaction: Check ID: too many IDs locked - .sieve with 100+ redirects ( 201 actually ) #define DUPLICATE_LOCK_MAX_LOCKS 100 It's not corresponding with sieve_max_redirects = 310 or sieve_max_actions = 320 On dovecot 2.3.16 version DUPLICATE_LOCK_MAX_LOCKS is not implemented and redirects work correctly. Thank you. Vladimir Gulas.
