E-mail messages

We just had devmon stop working while we was out at lunch and had over 1600 e-mail messages come in. So I logged into the server and stopped sendmail, so that the e-mails would stop going out. I have everything up and working but need to know how I can clear out any left over messages so that when I start sendmail back up I won't get another 1600 messages saying recovered.

After I get that resolved what is the best way to have hobbit only page out purple for the devmon process itself and not for any device devmon is monitoring?

Thanks,
