Relay single Domain to relayhost?

[polysign]

Dear Motokochan,

you were right! It was that simple...

So all I had to do is remove the domain from the /etc/postfix/ispcp/domains list and rebuild the domains.db using postmap. Then I manually changed the DNS Zone for that domain by changing the IP of the mail.domain.com entry.

It's no clean setup and I don't know how ispcp will handle the manual removal of the domain in the domain.db. But I hope as long as I don't edit the email-settings fro that domain, it will be allright

Thanks again.
