Daniel -
I thought it was sufficient to look into the headers
of the offending email spammmers and add these respective
IP address and/or host names to the /etc/mail/access file,
but I am beginning to suspect that these headers could be
easily spoofed with bogus entries, right?
I am really getting tired of adding in entries into the access
file, and writing email filters (in thunderbird) for patterns
dumping spammers into the trash - and yet - I am still forced
to review the trash for entries that should not have been trashed.
Seems like a real chore and a losing proposition...
What do admins of sendmail use, besides spamassasin?
See
http://harishpillay.livejournal.com/44948.html. I have been using
milter-greylist since late 2006 early 2007 and all I can say is that
spam has been reduced to less than 1% of what it used to be.
I don't use spamassasin or any other filters for greylisting does
it very well for me.
I am running that on a machine that receives mail for a domain
that has about 10K users and ever since it was turned on over
3 years ago, the user base has been very happy.
BTW, the system is running on a Fedora 13 system right now
but started life on a Fedora 7.
Regards.
