You could also parse the log files. I think it's quite trivial to check 
for each user what the last match was of 'imap-login:' (grep | tail -1). 
That way, you can be sure it really was a login.

Ofcourse, it rather depends on how old your log files are, you might not 
have anything more than a few weeks old.
