Hi Steven,

adding

smtpd_recipient_restrictions = [ ......],
reject_rhsbl_client
blackhole.securitysage.com,
reject_rhsbl_sender
blackhole.securitysage.com,
reject_rbl_client relays.ordb.org,
reject_rbl_client blackholes.easynet.nl,
reject_rbl_client cbl.abuseat.org,
reject_rbl_client
proxies.blackholes.wirehub.net,
reject_rbl_client bl.spamcop.net,
reject_rbl_client sbl.spamhaus.org,
reject_rbl_client opm.blitzed.org,
reject_rbl_client dnsbl.njabl.org,
reject_rbl_client list.dsbl.org,
reject_rbl_client multihop.dsbl.org


to the "main.cf" on the mailserver already reduced the amount of spam by
approx. 50% on our server [....] means that you should leave your
current policies like "permit_mynetworks" how it currently is.

Postgrey http://isg.ee.ethz.ch/tools/postgrey/ has also been mentioned
to reduce the amount of spam quite well. I'll use that on one of the
upcoming mailservers, so I don't have any experience with that up to now.

However both recommendations just work on mailservers directly accepting
the mail,

best

Well, I'm still getting mail from this list, so it's not blocking everything.
It will take some time to determine if I've blocked things I don't want
blocked. So far I have no new spam in the inbox in over an hour. That is
very good. Far better than 50%. Thanks

Steven
