Hi!
About 4-6 MUA Thunderbird 60.6.1 are going to connect with dovecot
2.2.13/IMAP (debian 8) and are using the same user/password. This setup
works for years flawless (updated clients and serversoftware).
Since a few weeks there is one major trouble:
I one of the client moves a mail from the inbox to a another IMAP-Folder,
most of the moved mail are moved for the moment. But an unstable period
later, the mails are moved back to the inbox. In rarely cases, the moved
mail is copied (one in the inbox, one in the destinationfolder).
Now I have to check, if this a Thunderbird-Issue or is this a
dovecot-issue. For that reason, I will activate the extended logging of
dovecot.

It works: dovecot logs to three differnt logfiles /var/log/mail.dovecot-*
It doesnt work:
plugin {
mail_log_events = delete undelete expunge copy mailbox_delete
mailbox_rename
mail_log_fields = uid box msgid size
}
I cant see such events in the logfiles. Which switch is to turn on to log
all events?
Or do anyone know the reason for the annoying
"copy/move-the-mail-back"-issue?
Thank you in advance for all inputs.
regards, martin

But I think there is another problem which I have to solve first. I recognised that the maildelivery stops after turning on the logging to the three files. The incomming mails are held in the mailq, in syslog appears relay=dovecot, delay=0.13, delays=0.07/0/0/0.06, dsn=4.3.0, status=deferred (temporary failure. Command output: Can't open log file /var/log/mail.dovecot-error: Permission denied ) In /var/log/mail.dovecot-error are lines like 2019-04-14 10:16:18 auth: Warning: auth client 0 disconnected with 1 pending requests: Connection reset by peer Here the output of ls -la /var/log/mail.dovecot-error -rw-r--r-- 1 root root 21259 Apr 14 11:24 /var/log/mail.dovecot-error If I turn the extended logging off, all works fine. `postqueue -f` releases all held mails to their boxes. Any hints for me? Thank you! martin
