We have a Postfix server that sends mail everywhere except one domain.
That one domain, we'll call it "problem.com" is protected by Postini spam filtering. We think that has something to do with it. So, we logged into the Postini account, and setup rules that should allow this email through. (The email is a form submission from problem.com's website).
The mail still doesn't come through.
So, I was wondering can I configure Postfix to send the email directly to the mail server instead of routing mail via MX records for this one domain? If we can deliver these forms from the website straight to their exchange box, the problem is solved.
Thanks in advance.
PS. Please provide examples of how to configure the Postfix box in your answer.
