forward mail from ispcp to exchange

[kilburn]

If you have both locally managed and g-mail managed domains, then for the exchange ones you have to:

1. Make sure that the DNS MX records point to the exchange server. To achieve that in ispcp, update both "/etc/ispcp/bind/working/domain.tld.db" *and* "/var/cache/bind/domain.tld.db" (don't forget to update the serial!!). Then run "rndc reload domain.tld" and check that "host -tMX domain.tld" run from the server correctly returns the exchange hostname/ip.
2. Comment out the domain from both "/etc/ispcp/postfix/working/domains" *and* "/etc/postfix/ispcp/domains".
3. Run "postmap /etc/postfix/ispcp/domains".
4. Reload postfix (/etc/init.d/postfix reload) just to make sure that the changes are acknowledged.

... and that should do it. Post your logs if it's not working for you.
