Williamwlk,

Looks like your mail server thinks this is a spam site, or is blacklisted!  You need to find the spam settings and get the site off the blacklist!  I have experienced simillar problems before and it was related to spam and blacklists!

Let us know how you make out?

Yahoon have these sort of problems. They are having very strict rule against spamming. I have faced the same issue several time.

The best to fix this issue is just change the IP address of your mail server, but before changing the IP address just that is also not black listed.

Changing of IP address is the best way because If you will go and contact yahoo those guys will take lost of time to respond, till the time you will face the same issue.

Once you will change the Public IP, after a week or so your IP will be removed from blacklist.
