For anyone thinking of running a private mail server off their home DSL line, don't do it. It's very likely your IP (even if static) will be in all sorts of spam block lists. Instead, either use your ISPs mail server as a smarthost (if they allow it) or (better imho) get a small VPS of your own (e.g from Linode) and: 1). Install open dkim and set it to sign all your outgoing mail (make sure to add the relevant DKIM TXT records to your domains) 2). Add SPF records to all your domains 3). Make sure your server's IP has reverse dns setup Your mail should then happily sail through all but the most brutal of spam filters.
