rbtux Wrote:remove the domain from the postfix virtual table/hash file

But how do we remove it so that ispcp does not add it back in there again ?

I can't seem to find the right place to remove a domain so that the postfix system no longer thinks it has control of it.

I once set up a domain here, but then chose to run it's mail on a different server, and just can not find where to remove from the system so that it does not get added back in again.

Your help appreciated.
