[plug] cannot send mail to certain domains

[Matt Kemner]

Hi Jon

You seem to be confusing the two seperate issues here.

The "cannont send mail to certain domains" is a DNS issue.  The "I can not 
receive email" is a local postfix configuration issue.

On Wed, 3 Feb 2010, quoth Jon Miller:

Where did the 192.168.2.247 come from?

Is that anywhere in your postfix/main.cf or /etc/aliases or /etc/postfix/virtual?

Because the server doesn't realise the message is for itself, so it tries 
to pass it on, only to discover it is talking to itself.
