[Exim] Some domains reject Just my exim connections

I am trying to send email to some domains and they are rejecting me. I
have confirmed that others are able to send email to the mx hosts of
these domains.

ex: americancentury.com

I cant even telnet to port 25. Telnet to port 80 times out. Browsing
http on port 80 works.

Please share your thoughts.

Thanks.
