Just for everyones information I have had trouble with this, and it was
fetchmail that was causing my problems.  I had been using it to get my mail
from my isp and it turns out that it was leaving the mail on their server.
Mail piled up and they blocked me for it.  I am now getting it through XFmail
which is my noraml client and making sure that it gets removed from the server.
Then again my problem was that I couldn't send mail to anyone, not even myself.

HTH.
