Hi Ron, you are not alone with this problem, infact everyone everywhere, some time or other has trouble sending mail to certain domains, yahoo, aol, hotmail, etc.
It isn't neccessarily your hosting providers fault but rather a change in the way certain domains like the above, have recently changed the way they filter spam and bulk emailing.
If you view the 'Services' forum (or use the search option), you will find quite a few threads on this subject.
rDNS seems to be the main culprit for returned emails, but there are many others like spf records, etc.
There are also ways to help making sure your emails get through. Yahoo for instance is a case of sending an email to a yahoo account and then adding the received email to the trusted list, this then filters through the yahoo servers as a trusted sender adddress and that should cure that.
AOL is a pain, you have to fill in an online form to add your domain to the trusted whitelist.
Hotmail seems like a hit and miss affair to me, again I think if someone adds your send email to their trusted list, the rest also are allowed through.
The main point is making sure that your domain and records (rDNS for i.e)are setup correctly before you follow any of thw above.
Hope that helps a bit
