is it possible to run a script right after the IMAP/POP3 session was started? I know about post-login scripting but this is probably not what i'm looking for. I need to run a script which will know PID of process running IMAP session (so it must be already started). Thank you.

The only way currently would be to create a new plugin that executes the script. But I added some new code that would make it possible with post-login scripts: http://hg.dovecot.org/dovecot-2.2/rev/9ef23179892a

With this you could configure your userdb for example:

userdb { .. default_fields = mail_pid=%{session_pid} }

Now in your post-login script you’ll have MAIL_PID environment containing the PID.
