[plug] Help with spam

[Evan Lau]

Hi guys,

I'm trying to figure out some spamming issues with our mail server. In the
sendmail log, the following two lines are just an example of what's going
on:

Jul 24 14:05:33 zeus sendmail[618]: OAA00618: from=www, size=1484, class=0,
pri=
601484, nrcpts=20, msgid=<200107240605.OAA00618 at zeus.starwon.com.au>,
relay=www@
localhost

Jul 24 14:05:48 zeus sendmail[620]: OAA00618:

xdelay=00:
00:15, mailer=esmtp, relay=mailin-04.mx.aol.com. [205.188.156.249],
stat=Sent (O
K)

There are plenty more examples of this. Of course, we don't want this to
continue as we don't want to end up on the "blacklist" of the Internet.

The problem is I don't get what "from=www" means, along with the part
that says relay=www at localhost. If anyone could help out with that please
do :) I guess the more important issue is how do we stop this. I have tried
the "access" file of sendmail, but doesn't quite seem to work.

Would much appreciate you guys giving me your thoughts on this. Thanks!

Cheers,
Evan
