altincit,

More and more hosts are requiring SMTP authentication in order to send email. This could be the cause of your mail getting rejected.

-Set SMTP authentication(use same username and pw as your mail account) in your mail client
or
-Hit send/receive before sending your email. Some hosts will allow you to send email only within a certain timeframe after authenticating.

If these things don't get you any farther, you'll need to contact your host to see what's up.
