I run Postfix on my home Desktop machine (always on), it basically only manages E-Mail to and from my hosting service which is where most of the domains that I actually use for my 'public' E-Mails reside. For outgoing E-Mail my postfix server just sends everything out to my ISP's 'smarthost'. -- Chris Green
