script for zapping Swen at the pop server

[Ron Johnson <ron.l.johnson@cox.net>]

(Mailfilter only checks headers, so can't see filenames of
attachments.)

I've got this in my crontab:
*/5 * * * * (/home/me/pop_zap_msft.py && fetchmail -s)

The rc (named ~/.pop_zap_msftrc) has this *exact* format:
SERVER=pop.someisp.net
USER=snarfle
PASS=blah

Hope you find it useful....
