Answer : Clear sendmail mail queue automatically

You should probably just leave the queue alone and let it work itself out. If messages are in there, there is a reason, and forcing the queue probably won't help. Most of the time it's due to delivery problems (recipient's box is full and the server wont' accept any more, being greylisted, or even backscatter). Sendmail will keep trying to send these are regular intervals on its own.
