Any way to prevent my outgoing email being detected as spam?

I am getting 451 4.4.1 reply: read error from ...





This is not through yahoo or web based email. It is through my local isp. I am on dial-up. I am not on ATT/yahoo isp either.





I read online that smtp server thinks my email is spam it is not. Is there a place I can register my emails at no charge?





Sorry if wrong category.

Contact your ISP help desk for an explanation %26amp; resolution to this problem. It may be a simple error, or your computer may have a trojan that is making it a zombie %26amp; sending spam without your knowledge, altho it would be unusual to do that on a dial up connection
