    I want to clean out an IMAP "folder" (actually file $HOME/mail/Spam).
    We have about 10,000 users and our users don't check their spam
    quarantine often, so our policy is to remove messages after 14 days.

    I know how to:

    1) recursively pull each Spam folder in existance (for x in `ls
    /home/*/mail/Spam`; do ....; done)
    2) Use grep and awk to pull each message and its relative data (grep the
    date, parse it)

    What I'm not sure of is how to remove a message from the spool itself.
    Should I just use grep and/or sed to "pull until new From header", then
    remove those lines from the spool manually?

    This would be easier if I could use IMAP, because then I could use the
    built-in PHP functions for imap to check dates and remove messages.
    Problem is, we don't know the user's passwords (they are hashed).

    Any other ideas? Thanks!

    -Matt
