#1 get a mail account on yahoo so you can send e-mail to yourself and
check it to see if it's delivered...they're free

#2 I suggested that you try an SMTP connection via telnet so you can
visually monitor what is being said...did you do that?

#3 Is it possible that your ip address(es) are listed in some DNSBL?
Have you checked?

#4 Is it possible that the e-mail is delivered to a 'spam' directory
instead of people's INBOX?
