Log watching is actually pretty good - but another option is to monitor
the $conf/proc/ directory.  When someone is connected there will be a
file in there with their username and what folder they currently have
selected.

Your cron job could just grep that folder and run if there was a file
with the required username present.

[brong at imap1 proc]$ grep brong *
31327:web6.internal [10.202.2.215]	brong	user.brong

Getting Cyrus to actually trigger something is much more complex - but
you could easily do something with an inotify on the directory if you
want smaller than a minute resolution.
