I would check www.spamhaus.org , which is a spam block list site, on your mailing IP. You may be on a blocklist due to suspicions of spam activity. This typically happens if your network is infected with a spam worm.
Thanks for your input, I really don't think it 's a SPAM problem however I did look and did not see anything that could be the problem. The problem all started with outlook express resending the same email over and over filling the in box to everyone I sent it to. Not just one email, all emails I would send. So with that, I think my problem is with outlook express however, I can't get anyone to tell me how to fix or reinstall outlook express. I called my ISP and all they will say it's not them and they don't support outlook express (Charter) I do believe the problem is in outlook express but I cant reinstall it or were to find it in my software to reinstall it.
