Hi Brian Everything you said makes a great deal of sense - thanks very much. I have changed the RBL settings, as you advised.
Yes, the load has gone up considerably, particularly, we are seeing a massive rise of spam traffic on this box (mainly on one or two of the domains 30 domains its responsible for) However, I have tried putting "proxy:" in front of my mysql maps and it stopped it being able to receive email. Presumably, I need to enable proxymap to get proxy maps to work. This is something I don't know how to do. This is what "postconf -d | grep proxy" returns: local_recipient_maps = proxy:unix:passwd.byname $alias_maps proxy_interfaces = proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks smtpd_proxy_ehlo = $myhostname smtpd_proxy_filter = smtpd_proxy_timeout = 100s There are no lines with proxy in my main.cf, do I need to add in a "proxy_read_maps"? If so what do I set it to? Incidently, here is a copy of my "mysql_virtual_mailbox_maps.cf" I did initially have a few problems getting this working. If I use proxy:mysql: will I need to change this? user = <postfixuser> password = <postfixpassword> hosts = localhost dbname = postfix table = mailbox #select_field = CONCAT(domain,'/',maildir) select_field = maildir where_field = username additional_conditions = and active = '1' #query = SELECT CONCAT(domain,'/',maildir) FROM mailbox WHERE username='%s' AND active = '1' Regards Jon [snip]
