local-host-names and external mailserver

[Tyrael]

Hi,
I set an External Mailserver for a domain (in the option tab).

If I try to send a mail to this domain from another account that is on the ispconfig server I get an error:
RCPT TO <address@domain.com> fallito: <address@domain.com>: Recipient address rejected: User unknown in local recipient table

I think this is beacause the domain is added in local-host-names also if the mailserver is set to External Mailserver in the options tab.

You must set the co-domain to external mailserver too, not only the website.

Thanks!
Now it's ok.
