I still hate spam

This is a quick follow-up to my previous post, "I hate spam." Adding the RBLs mentioned in that posting brought my spam count down to something more manageable but, unfortunately, the effect didn't last. My spam count has been edging back up and got to the point where it was definitely annoying again.

A post to the CentOS mailing list included three addition RBLs. I have added these to my spam gauntlet and they seem to have helped. My RBL configuration for sendmail now looks like:

FEATURE(`dnsbl',`bl.spamcop.net', `"Spam blocked see: 
http://spamcop.net/bl.shtml?"$&{client_addr}')dnl
FEATURE(`dnsbl',`cbl.abuseat.org', `"Spam blocked see: 
http://cbl.abuseat.org/lookup.cgi?ip="$&{client_addr}')dnl
FEATURE(`dnsbl',`sbl-xbl.spamhaus.org', `"Spam blocked see: 
http://spamhaus.org/query/bl?ip="$&{client_addr}')dnl
FEATURE(`dnsbl',`list.dsbl.org', 
`"Spam blocked see: http://dsbl.org/listing?"$&{client_addr}')dnl
FEATURE(`dnsbl',`dnsbl.sorbs.net',
`"554 Spam blocked " $&{client_addr} " found in dnsbl.sorbs.net"')dnl

spamcop and spamhaus are old friends. The new additions to the gauntlet are:

• The composite blocking list at http://cbl.abuseat.org/
• http://dsbl.org/ is currently offline due to a disk crash
• The Spam and Open Relay Blocking System at http://www.au.sorbs.net/

As with the previous addition of the SpamCop and Spamhaus RBLs, I have noticed a marked reduction in the amount of spam reaching dSPAM.

Cheers,
Dave
