Hi
Interesting this, when i set up Mercury, it says there MUST be an entry for the machine itself, (no domain), however this results in receiving email for anything at "ipaddress", is there a way to stop this, so it only receives email for domains the server controls?

I presume you mean something like this?
[Domains]
server: [123.123.123.123]
server: yourdomain.com
It's good practice, but I don't know if it is required by RFC's (I am no expert). I would be surprised if many servers supported that now. Also, I have never seen it used by any incoming mail.[quote]
However will this kill the "postmaster" function account?[/quote]
No. The postmaster account is postmaster@<internet name for this system in Core Config>
[quote]Will i have to create a rule that only says to process emails to specific domains (will still kill the postmaster account i think?)

As long as your (anti-)relaying settings are correct it should only accept mail for the domains listed in the [Local Domains] section.
