Well as far as I know SMTP is not blocked. I wanted to go through my ISP's server to begin with, because places such as GMail didn't like me. Yet everyone seems to love my ISP's server.
I had relayhost set to my ISP, but I musta had something wrong, because some people would get replies, while other people wouldn't.
