On the MAINserver, I have a several sites which share the same IP address as MAINserver.com (virtual servers).

The main server acts as a mail server . i..e. It's MX records point to the remote Exchange Server and all the other virtuals have an MX record pointing to the mainserver.


Recently, I added another site to the server and as it was a Dutch TLD (.nl) I was forced to use a different IP address. But that was fine and the email was pointed at the remote exchange server via the mainserver.com

Today, I have been asked to change from the remote IP address and set-up POP3 mail boxes. No probs, That's done. BUT IT DON'T WORK !
This is how the DNS looks:
============================================================================================
domain.nl xxx.xxx.xxx.xx
mail.domain.nl xxx.xxx.xxx.xx
www.domain.nl xxx.xxx.xxx.xx
domain.nl mail is sent to the High priority mail server mail.domain.nl
www.domain.nl mail is sent to the High priority mail server mail.domain.nl
============================================================================================

What have I done wrong or what should I change ?

Please
