Is there a difference between not setting #ssl_cipher_list = or setting to nothing ssl_cipher_list = or setting to ssl_cipher_list = PROFILE=SYSTEM Which is the best preferred way for default? Also, the docs say "You should usually prefer server ciphers and their order, so setting ssl_prefer_server_ciphers=yes is recommended." however this setting is =no by default. Why? Should it be yes or not?

Panic during IMAP APPEND
by Gedalya 30 Sep '21

30 Sep '21

I don't know how I can tell which mailbox is selected / being appended to. Mailbox format is Maildir. Filesystem is XFS. System was upgraded from 2.2.36.1 to 2.3.16, and it seems this started happening following that.

Broken links
by MAREN ZUBIZARRETA 30 Sep '21

30 Sep '21

Hello: We are using Single instance attachment storage (SIS). Recently we have updated to latest dovecot versión, and changed the storage system. After the change, we are perceiving that, for some random users and days, attachment links were not created. In some cases even the file itself is missing (we asume that this is because, if there is 0 links pointing to the attachment, it gets deleted, or not Created even). There is anybody else experiencing the same issues? Could it be caused from some bug? Any hint? Thnks for your help Maren Zubizarreta

Dovecot sieve filters
by j.emerlik 20 Sep '21

20 Sep '21

I'm have a problem where dovecot-sieve is used to run the script after moving emails from Junk Folder. config: imapsieve_mailbox2_name = * Imapsieve_mailbox2_from = INBOX.Junk imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_before = file:/usr/local/lib/dovecot/sieve/report-ham.sieve filter: require [ "vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables", "fileinto", "envelope" ]; if environment :matches "imap.mailbox" "*" { set "mailbox" "${1}"; } if string "${mailbox}" "INBOX.Trash" { stop; } if environment :matches "imap.user" "*" { set "username" "${1}"; } pipe :copy "sa-learn-ham.sh" [ "${username}" ] It's working perfectly. However, I have a problem after adding : if envelope :is "from" "*" { set :lower "from" "${1}"; } pipe :copy "sa-learn-ham.sh" [ "${username}", "${from}" ] then appears error in log file: Error: sieve: report-ham: line 1: the envelope extension cannot be used in this context (needs access to message envelope) Is possible to use envelope extension to get sender address after moving message from Junk folder ?

Mail error log polluted with dovecot imap errors
by Steve Dondley 17 Sep '21

I'm running debian bullseye. I've had issues running solr on debian due to some kind of bug I was able to patch by upgrading the os. After the upgrade, everything seems to work perfectly fine and the search feature in my client using solr now works. However, I get hundreds of these pairs of errors every minute in mail.err Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '102 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '103 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '104 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '105 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '106 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '118 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '132 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '133 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '134 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '135 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '136 Sep 17 04:47:52 email dovecot: imap: Error: ' Sep 17 04:47:52 email dovecot: imap(s)<8699><1eOe/CzMbOl/AAAB>: Error: fts_solr: received invalid uid '137 ...and so on The bug I patched also threw a similar kind of error: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=970692 I don't know if this is another debian issue or a misconfiguration on my end. I'm not sure where to begin to look. Can someone please point me in the right direction?

Unprivileged users can't use doveadm anymore in 2.3.16
by dovecot＠ptld.com 17 Sep '21

17 Sep '21

What happened in 2.3.16 to doveadm? You can no longer use the command as an unprivileged user like you could in 2.3.8 Roundcube uses "doveadm pw" to change users passwords and runs as user apache. This works in 2.3.8 but in 2.3.16 you get an error. doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 19: ssl_key: Can't open file /etc/letsencrypt/live/example_cert/privkey.pem: Permission denied I tried "doveadm quota get ..." from the console as user apache and got the same error. I then tried running just "doveadm" and got the error, it wouldn't even display the help output. So it appears to not be directly related to using the "pw" feature. Just to trouble shoot i gave full read permission to privkey.pem just to see if doveadm would work. Doveadm still would not run for user apache but gave a different error: doveconf: Error: ssl enabled, but ssl_dh not set doveconf: Fatal: Invalid configuration Was this requirement to read the privkey.pem always there or just added in 2.3.16? Is this a deeper issue considering the ssl_dh error? Is there a way to fix this? Is this by design unprivileged user can no longer use doveadm?

Issue between roundcube and newer dovecot 2.3.16 with doveadm pw
by dovecot＠ptld.com 15 Sep '21

15 Sep '21

Aki; I know most likely this isn't dovecot's fault, however upgrading from 2.3.8 to 2.3.16 broke the password plugin for roundcube. Im only asking if you might know what changes in dovecot might have caused this incompatibility so i can fix it myself or point roundcube in the right direction to fix it. I submitted a bug report to roundcube with details of the issue. https://github.com/roundcube/roundcubemail/issues/8200
