Yup, tried that yesterday. Tried again but still denying access.

OK, then I have to conclude that the problem is outside of the script. The possible causes that I can think of are

(1) SSL/TLS haven't been installed in the web server.
(2) Some network configurations, security policy on your web server, or firewall is restricting your access to the mail server.
(3) smtp.bizmail.yahoo.com is rejecting the IP address of your web server.

Statistically, (3) is most likely. I think you should talk to the web administrator, anyway.
