So, you'll need to set this in the zone files.
Normally in debian etch they are in /var/cache/bind/(*.db) - with a copy in /etc/ispcp/bind/working - you already learned about that :-)

the MX line in the zone files should be changed:
either you set the new hostname (with a point at the end) or the right ip number there - or you leave mail.domain.. and give the new ip address in the line where mail is defined...

orig, some lines:
IN MX 10 mail.domain.net.
mail IN A 123.45.67.89
www IN A 123.45.67.89

variant 1:
IN MX 10 mail.newserver.net.
mail IN A 123.45.67.89
www IN A 123.45.67.89

variant 2:
IN MX 10 mail.domain.net.
mail IN A new.ip.of.mx
www IN A 123.45.67.89

or similar...

there is an excellent book from oreilly about bind and dns :-)))

Cheers, J.

Actually, I tried these and a third and a fourth variant to no avail even before I read your reply. Problem is, that however I do this (and regardless of how many times I am restarting/reloading bind9), I get no updated replies from dig... (I got no ANSWER section). There is no DNS cache to flush like on windows and I can only suspect TTL settings interfering here but is that normal? I'll wait 86400 seconds and check dig again... Then I can start to think about paperbacks.

Btw the 3rd variant I tried (and which is still active) was:

Code:

IN      MX      10 mail.mydomain.net.
mail            CNAME   mail.mailserver.com.
www             CNAME   mydomain.net.

...as this is how my external "real" dns is setup - querying mail.mydomain.net gives me a CNAME to mail.mailserver.com.

And btw my mail.mailserver.com resolves to my external mail server IP fine.

Thanks again for watching!
