dovecot?
I’v not found any switch to do that.
Thanks and regards . Götz
Not sure why you haven't found
https://doc.dovecot.org/configuration_manual/config_file/config_variables/
You may use following log formatting
login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c %k
to get log content like
Dec 13 12:20:21 msg dovecot: imap-login: Login: user=<f...@example.org>,
method=PLAIN, rip=2003:e6:3a0c:7e12:106e:4562:cb72:566b,
lip=2a01:1000:6:9d:0:dead:beef:cafe, mpid=6476, TLS, TLSv1.2 with cipher
ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)
See what %c and %k translate to in that example.
