[Dovecot] logging

I am looking through the logging options and wondering if there are a couple of things that we can do

1. Logouts don't seem to show the IP address of the logout, we typically see multiple sessions at a time and wondering if there is a way to tie the logouts to an IP
2. POP logouts show the number of messages retrieved/deleted but I don't see a way to do this with IMAP, is there a logout option for this with imap?

Thanks
