Hello,

I'm currently playing with a number of dovecot instances to evaluate my "next generation setup" For now I run 6 instances of dovecot, one per docker container:

• 2x redirector
• 2x backend #1
• 2x backend #2

All docker container use syslog. And there the problems starts. Every instance identify itself as "dovecot" That's not helpful :-/ I tried to set an instance name but that change nothing.

My options are now

• let rsyslogd separate the sources by IP
• use logfiles files Are there other?

Currently the code use a fixed string "dovecot": https://github.com/dovecot/core/blob/master/src/lib-master/master-service.c#...

I would ask if it's possible to use the instance name as syslog identifier, too?

Did you try running rsyslog inside the container and forwarding everything to the endpoint? You can modify the configuration of rsyslog and explicitly set a hostname if needed.
