Webmail works, webform works except 1 domain

[ginkelb]

Hi There,

I've got a weird problem on my hands.

I have a clean installed Red Hat Enterprise 3 server with at the moment 1 domain hosted on it.

On the website of this domain we are running an number of forms witch output to email. When someone uses such a form the email sent does get delivered to an external mailbox but fails to be delivered to any mailbox in 1 specifix domain.

Mails sent through webmail however DO get deliverd to this domain.

How can it be that mail doens't get deliverd to a specific domain through webforms when it does trhough webmail?

Hope someone can help,
Bas van Ginkel

Set a return address in the script and look at the error it returns. Or check the maillog
