I'm now working through this and have hit a bit of a problem.  The post in 
question reads as follows:

This would appear to be the sticking point.  The aliases file doesn't 
generate fully-qualified Email addresses, only local parts.  How do I 
ensure that a message to announce at foo.com doesn't go to announce at bar.org? 
This must be doable, because if it's not, then this defeats the whole 
point of doing this in the first place.

Presumably I need to do this in postfix/main.cf somehow but I'm at a loss 
as to how to do this.
