determine whan the mailbox was last accessed

[Eugene M. Zheganin]

Hi.

Some time ago I used the seen per-user databases to determine when the
mailbox was last accessed (and it was easy - it was the time of seen
database modification - for IMAP users, of course). Now the seen
database has migrated into one file for all users, and I'm not sure how
to do this. I will really appreciate if someone will describe how to do
this.

Thanks.
Eugene.
