I''ve recently outsourced spam filtering. I have to pay per domain and per user, so the domains I host for friends aren''t serviced by the spam filter service. I don''t want spammers to be able to bypass the spam filter service and send mail directly to my server. I found that other people have had similar needs and exim was able to satisfy them, but the configuration posted was for a generic exim4 setup and not with Debian''s specific configuration. I''ve broken things in the past messing around with configuration files, so I am wondering if someone can tell me precisely what I need to change to get this recipie to work. (Debian stable, unified config file).
