Title: New command to unlock mail as a failsafe

I've noticed the mailer can get locked up where the LOCK_FILE never gets removed. This command blows the file away if it's over 4 minutes old (I suppose it should be a setting). Run it as a cron job every X minutes to feel better about things (or at least get notified when the mail is locked).
