I have a server at a hosted site where I send emails to users who register on our website. Any replies get sent to a different server. This works but any emails that go to hotmail accounts get marked as junk.

Mail gets sent from smtpout.abc.com (IP
I have my PTR set to resolve to smtpout.abc.com
My SPF is set "v=spf1 a mx ip: ~all"
My MX is set for mail.xyz.com (IP

I can successfully sent and recive mail for the abc.com domain but Hotmail doesn't like it. I don't think it's an issue that my MX points to a different domian is it? Any ideas?

Here's a copy of the header that hotmail sent to Junk:

Wanted to add that smtpout.abc.com does not receive email. (Port 25 is blocked on the firewall.) Going to try allowing incoming mail on smtpout.abc.com and see if that makes a difference.

ip: is not valid in a spf record. It should be ip4:

Have you checked the IP address of your sending server is not in any RBL?
You can use the tool at http://www.completewhois.com/rbl_lookup.htm

Other than that there is little you can do. Hotmail have a propietry spam filter which is pront to false positives from some senders for no aparent reason. Hotmail wont tell you why it is classed as spam.
