Send mail to two different routes

[NoWittyName]

We are implementing a new CRM system which is to use exchange to send out mailings to our customers, our outsourced anti-spam company does not allow this, so I need to be able to send mail from the CRM server using DNS lookup, but use another route for all other mail. How would it be best to acheive this?

Also is it possible to prioritise regular users mail over the marketing mail which we send from the CRM?

Thanks in advance

If it is to use Exchange but your anti spam company doesn't allow it and then say you want to send it from CRM, isn't that then no longer an Exchange issue?

I'd give the CRM a public IP of its own that isn't Exchange, pipe it through the firewall, add an rDNS name as spamlist.yourdomain.com and then start pumping that spam.

Since you aren't using Exchange to do it, prioritising won't be an issue.

Thanks for the reply, the CRM system uses exchange to send mail, so it must be processed from here, I was hoping I could Deny the CRM IP on the primary connector and enable it on another?

Why do you need to use Exchange to send it? Sounds like all you want to do is throw the CRM mailshots through the Exchange connector.

Edit the CRM headers to look like the Exchange server and push that straight to the external provider.

This is a new system which is currently under development by our supplier, I am old it needs exchange to send the mail. I'll ask the supplier some more and see if I can resolve
