If you are blocked because of Spamhaus' PBL you are on an consumer dial up (http://www.spamhaus.org/pbl/) and should not send mail directly to MX. Instead use your providers SMTP relay. http://www.postfix.org/BASIC_CONFIGURATION_README.html#relayhost http://www.postfix.org/STANDARD_CONFIGURATION_README.html#dialup > So I was thinking..

Look at http://www.postfix.org/postconf.5.html#relayhost or at http://www.postfix.org/postconf.5.html#sender_dependent_relayhost_maps in case you don't want to relay all sender through your other server. > Is this possible and if so, any pointers/suggestions on how to go about > doing this?
