Hi there
I'd like to change my setup to log the _actual_ IMAP user's login, rather than the UNIX username. My system uses a virtual uid setup with qmail, where the mailboxes are owned by the 'vmail' user and authentication is via checkpassword using user%domain (ie email, just with % instead of @). So dovecot is recording _all_ logins as:
imap-login: Login: user=<vmail>, method=PLAIN, rip=127.0.0.1,lip=127.0.0.1, secured
That means your authentication changes the username.
passdb checkpassword { args = /var/qmail/bin/qmail-vauth }
Most likely qmail-vauth changes USER environment to vmail. If you can't edit qmail-vauth directly, create a wrapper script that unsets the USER environment before calling Dovecot's checkpassword-reply.
