PEAR Mail won't connect to gmail, throws error

Solved. Bluehost is blocking the port and they won't unblock. Hope this helps someone else.

I am using the PEAR mail script given in this code example: Send email using the GMail SMTP server from a PHP page

I am on Bluehost, and when I try to connect to Gmail, I get the following error:

Failed to connect to ssl://smtp.gmail.com:465 [SMTP: Failed to connect socket: Network is unreachable (code: -1, response: )]

What can I do to further debug/track this down?

Thanks!

The host was blocking the port.
