When postfix connects to the FQDN dur.bounceme.net it uses the external IP address:

What's causing the FQDN to behave this way?
Can I, and should I, and how would I, configure dur.bounceme.net to resolve to 127.0.0.1?
dur.bounceme.netresolves to70.71.113.158– Ulrich Dangel Aug 28 '12 at 12:54postfixis correctly configured, especially the parametermydestination. See postfix.org/postconf.5.html#mydestination – angus Aug 28 '12 at 21:50
