Jeg bruger ssh til at logge ind på maskinen - den har fast ip. Den har ikke 
noget problem med at blive brugt af kmail (det mail program jeg bruger 
normalt) til at sende fra, fra $mydomain. 
Når jeg så logger ind på en anden maskine jeg har ståenden ude i byen og 
prøver at bruge postfix serverne som smtp-server sender den også e-mailen... 
Det vil jeg ikke have - det er med bbj@xxxxxxxxx e-mail adressen jeg tester 
med - det er nemlig ikke det domæne jeg har sat postfix op på.

Det skal lige siges at jeg ikke er "mail" ekspert - iptables og routning er 
nemmere i mine øjne og øre :-)
