A user's last access time

Dear Colleagues,

Is there a file or directory within a user's Maildir, whose date of modification or access indicates the last time the user accessed his/her E-mail via IMAP or POP3?

I'd like to figure out the time a user last logged in into his/her mail account, not the last time a mail was delivered to the INBOX.

This information is probably available in the log, but a file which is touched each time a user accesses his/her mail, is more convenient.
