I'm trying to block a virus package from being emailed to one of my users...
Nov 8 15:49:18 white sendmail[22324]: PAA22324: from=<jennifer@elyproperties.com>, size=0, class=0, pri=0, nrcpts=0, proto=ESMTP, relay=[67.92.168.231]
I've tried
access-list out_list deny tcp host 67.92.168.231 host 128.104.92.10 eq smtp
and
access-list out_list deny ip 67.92.0.0 255.255.255.0 any
I have a PIX 525
