Error: Mailbox INBOX: Sync failed
by Jos Chrispijn 02 Dec '20

02 Dec '20

Just saw in my logfile this line appeared: imap(xxxxxx)<56614><CMMJw9i0aoBSsH9H>: Error: Mailbox INBOX: Sync failed for mbox: Expunged message reappeared to mailbox (UID 174550 < 174552, seq=11, idx_msgs=9) Looks like messages' UIDs are mixed up? I thought that if Dovecot sees broken X-UID headers for "new" messages, they're silently fixed? Can you tell how I can correct this error/warning? Thanks! BR, Jos

Bug report: invalid \HasNoChildren in response when asterisk is used in the name
by Merijn Schering 01 Dec '20

01 Dec '20

Hi, I'm using dovecot 2.3.4.1 (f79e8e7e4). I have created a folder called "Test with *". Now when I do a command: A3 LIST "" "%" RETURN (CHILDREN STATUS (MESSAGES UNSEEN)) It responds: * STATUS Test with * ( MESSAGES 0 UNSEEN 0 ) * LIST ( \HasNoChildren \UnMarked ) / Spam But it actually has children! This only happens when I use a * character in the name. I hope you can fix this some day. Thanks! Best regards, Merijn Schering Intermesh https://www.group-office.com https://twitter.com/GroupOffice

director_username_hash = %d and doveadm director map
by Ralf Becker 30 Nov '20

30 Nov '20

Our directors hash by domain (director_username_hash = %d), as some of our users share folders with other users of the same domain. We now started using director tags to map domains to their backends. Unfortunately doveadm director map seems no to work with director_username_hash = %d user hash mail server ip expire time <unknown> 432784257 10.44.88.1 2020-11-23 13:10:55 <unknown> 4244233328 10.44.88.1 2020-11-23 13:13:55 <unknown> 1913982503 10.44.88.1 2020-11-23 13:15:40 How can I check to which backend / IP a domain is maped, aka how is that hash calculated? doveadm director move seems also not to do anything meaningful for %d, or at least I have not found out how to use it to move a domain to a different backend.

A probably dumb question, but I'm stumped
by Christy S 30 Nov '20

30 Nov '20

Hi folks, I'm stumped on an error we're getting in dovecot after upgrading ubuntu. I will say up front that I'm far from a linux expert. I'm helping my husband by managing a virtual private server to handle his domain, including its email. We set this up two years ago and once I finally got the mail working, it's been humming along just fine since, until two days ago when I performed the ubuntu upgrade. Now, when we try to send mail through his domain thunderbird gives this error: Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. Note that it says this, but the mail isn't actually sent at all. We are using SSL and have been since the beginning which might be part of our problem, but I'm not positive. A google search suggested adding two lines to the 10-ssl.conf file. ssl_dh = </usr/share/dovecot/dh.pem ssl_cipher_list = HIGH:!DH:!aNULL I did both of these things and restarted the server completely, but no luck. looking in /var/log/mail.err I see this. Nov 29 14:08:56 kylesmith-music dovecot: imap-login: Error: Failed to initialize SSL server context: Can't load SSL cert ificate: error:140AB18F:SSL routines:SSL_CTX_use_certificate:ee key too small: user=<>, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, session=<t4qrdkS1kPNLFhL4> What's interesting is that last line only showed up after I added the two lines to the config file. My guess is I need to do something with SSL, update it maybe? But I don't want to go fiddling around purely on a guess and potentially break things even more. So, any of you much more linux familiar types want to point me in the right direction? Thanks! Christy

Repo for ubuntu focal 20.04 LTS
by Sébastien Riccio 27 Nov '20

27 Nov '20

Hello Dovecot, As the new ubuntu LTS 20.04 seems to be out, I would like to ask if there are any plans to add a repo like it already exists for 18.04 LTS. We planned to upgrade our 18.04 LTS boxes to 20.04. It has it’s own dovecot packages (2.3.7 at the time of writing this), but I would prefer we use your repositories like we do with 18.04. Kind regards, Sébastien

Dovecot alternatives with good i18n support?
by David Bürgin 26 Nov '20

26 Nov '20

Hello! I’m interested in exploring alternative IMAP servers that have good support for internationalised email, such as support for SMTPUTF8, IDN mail domains, Unicode local-part, etc. etc. If you used to use Dovecot, and found an alternative that does such things well, I would very much like to hear it. Thank you, -- David
