Hi Hans.. I'm aware of what you are saying, but this is not what I'm asking. (or I'm misreadings your reply)
I've got one main domain: example.com
For that account, I've got one co-domain: the2nddomain.com
Going to www.example.com
, example.com, www.the2nddomain.com
and the2nddomain.com works fine.
The client has got email setup for @example.com
Now he also wants an email@example.com
It's okay with him if it gets forwarded to the @example.com address.
(note that the MX record for the2nddomain.com is setup okay.)
So.. Question is.. How do I get ISPconfig to accept email for the2nddomain.com without creating a "main domain" account for it.
