[Dovecot] mail_log_events, but who exactly triggered events?

Hi.

mail_log_events is nice addition but how to log who exactly triggered particular event? For example 5 users from 5 IP addresses uses single imap user/mailbox.

One of them deletes email and I'm logging delete related events. The only logged thing is:

dovecot: imap(user): delete: box=INBOX, uid=673287, msgid=<some@thing>, size=1230

which tells me nothing about who triggered it actually (note all 5 users were logged in at deletion time)

How to solve this problem?

Thanks,
