Spam is on the rise again and once again I have to waste time trying to
slow the flow so that my clients quit bugging me about the stuff. I just
delete it, why cannot they? Because it is my job to make the servers
automagically whisk it all away.
Anyway, to the topic. I currently only use spamcop for rbl. I trust
spamcop to not have false positives very often if at all. Are there any
other good rbl's that are trustworthy in this respect?
My favorite: sbl-xbl.spamhaus.org. I include the following line in my
sendmail mc file:
FEATURE(`dnsbl',`sbl-xbl.spamhaus.org')dnl
I also use greylisting, which blocks about 75% of all incoming mail. (See
FreeBSD ports: /usr/ports/mail/milter-greylist )
