Good day Guys I am getting this error message in the logs. dovecot: imap-login: Error: net_connect_unix(/var/run/dovecot/stats-writer) failed: No such file or directory Running Debian Buster. With a bit of googling, I tried the suggestions of: https://forum.iredmail.org/post67042.html#p67042 https://git.ispconfig.org/ispconfig/ispconfig3/-/issues/5343 But still this problem is persisting. Here is the config. ~ # cat /etc/dovecot/conf.d/20-dovecot-stats.conf service stats { unix_listener stats-writer { user = dovecot group = mail mode = 0660 } } ~ # ls -la /var/run/dovecot/stats-writer srw-rw---- 1 dovecot mail 0 Nov 21 17:00 /var/run/dovecot/stats-writer Could anyone please shed an idea or tip of where more too can I look. Many thanks Regards Brent Clark

I have been following the tutorial here: https://www.linuxbabe.com/mail-server/block-email-spam-check-header-body-wi… I notice that when I log into my mail via nextcloud mail, there is no spam folder. Is there something further I need to do so it is generated?

Can't unsubscribe from public mailbox when dsync multi-master is enabled
by Salatiel Filho 25 Nov '21

25 Nov '21

Hello, I am trying to build a dovecot environment with 2 servers with dsync master<->master replication. Everything works just fine, one can login in any of the servers and see and manage their mails. The problem I see is that one can not unsubscribe from public mailboxes. Let's call the servers server1 and server2, both of them have an imap webui pointing to localhost, just to make the test easier. One subscribes to a public mailbox connected through the webui on server1. A few seconds later the same user can see the subscribed mailbox on the webui on server2 just as expected, but if he tries to unsubscribe it will not work. The public mailbox folder will still be subscribed to and visible. There is absolutely nothing on the logs, but I know it is related to the dsync replication because if I shutdown any of the servers, I will be able to unsubscribe just fine, UNTIL the shutdown server is powered back on and replication starts again, and, in this case, the previously unsubscribed public mailbox will just reappear. Is this a bug or am I missing something in my configuration?

Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted
by Jesús Ángel del Pozo 25 Nov '21

25 Nov '21

Hello, I know maildir format does not allow to delete INBOX as stated in https://dovecot.org/list/dovecot/2016-January/102988.html. Nevertheless, even though I deleted the entire Maildir manually with rm -rf, doveadm backup fails with "Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted". I would like to make a user's maildir backup to a different folder. For example: rm -rf /tmp/zbbb/; doveadm backup -u test(a)disguised.domain.com maildir:/tmp/zbbb/ But I keep receiving this error message: Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted Do you know what might be causing this problem? If I use sdbox instead of maildir, the backup works: rm -rf /tmp/zbbb/; doveadm backup -u test(a)disguised.domain.com sdbox:/tmp/zbbb/ However, I would like to use maildir format for the backup as all my mailboxes use this format. Regards,

sieve discard option debug
by Jose Manuel 24 Nov '21

24 Nov '21

Hi, i have a question if someone can help me with this. My sieve file configuration is this: cat enabled_script.sieve require ["fileinto"]; if header :contains "subject" "@ggmaail.com" { fileinto "INBOX.Spam"; } elsif header :contains "subject" "TW" { discard; elsif header :contains :comparator "i;octet" "X-Spam-Status" "autolearn=spam" { discard; } When the condition is true and a mail is discard i can not discriminate in the logs what was the reason. 1) "subject" "@ggmail.com" or 2) "subject" "TW" I can only see this message over the logs: February 15th 2021, 17:39:33.000 lmtp(mail(a)mail.domain)<27188><kJhTEMWjKmA0agAAaUS+oQ>: sieve: msgid=<001701d703b9$234a8b80$69dfa280$(a)correo.es> <001701d703b9$234a8b80$69dfa280$(a)correo.es>: marked message to be discarded if not explicitly delivered (discard action) (Note: i changed the domain names) My question is: Can i setup or add any option in my sieve filter for more info about the discard reason ??? Any rules together with the discard option ? I am out of idea about it. Thanks in advanced!!!
