Thanks. However, I'm unsure what the syntax (or method) to drop the offending rule is. Here's the contents of the MailrulesReject:
MailrulesReject=*@*.excite.com:*@*:EXCITE REJECT,*@*.rocketmail.com:*@*:ROCKETMAIL REJECT,*@*.tekmailer.com:*@*:tekmailer REJECT,*@*.youask4it2.*@*:*@*:youask4it2-2 REJECT,*@ATT.COM:*@*:ATT REJECT,*@YAHOO.COM.CN:*@*:YAHOO.CN REJECT,*@aol.com:*@*:AOL REJECT,*@myonlinespecials.com:*@*:SPAM REJECT,*@netzero.net:*@*:NETZERO REJECT,*@superdealz.com:*@*:SUPERDEALS reject,*@quickdeals.biz:*@*:QUICKDEALS REJECT,*@swordfishmedia.biz:*@*:SWORDFISH REJECT,*@swordfishmedia.net:*@*:SWORDFISH REJECT,Aadmirable@NETSCAPE.COM:*@*:aadmirable reject,Garcia-BaconAngela8t@hotmail.com:*@*:GARCIA REJECT,comp-whiz@optusnet.com.au:*@*:compwhiz REJECT,youask4it2@*:*@*:youask4it2 reject,*@hotmail.com:*@*:HOTMAIL REJECT,:*@*:No sender REJECT
The last one is the problem child.
