Hi.
I'm no sendmail expert, so perhaps someone with more of a clue than I
do can tell me if I've got a pilot error.
I installed the /etc/mail stuff a few days ago, and added a few sites
to domains.txt, specifically:
BIGFOOT.DALTEK.NET^M #blocked. contact postmaster
I did a ``make install'' and HUP'd sendmail and checked the log to
see that it had restarted.
Just to confirm things, grepping for ``bigfoot.daltek.net'' in
spamsites.db says it's there, and grepping for ``spamsites.db'' in
/etc/sendmail.cf gives:
Kspamsites hash -o -a.REJECT /etc/mail/spamsites.db
I just received this:
Nov 15 23:50:50 gate sendmail[21528]: XAA21528: from=<associates@bigfoot.daltek.
net>, size=1874, class=0, pri=31874, nrcpts=1, msgid=<199711152014.OAA26126@merc
ury.gmds.com>, proto=SMTP, relay=punt-1a.mail.demon.net [194.217.242.134]
Shouldn't this have been rejected ? I've enclosed my complete .mc
if anyone's interested. The second bit was directly copied from the
stuff in /etc/mail.
Thanks for any suggestions.
