Audiovox PPC-6600 / PPC-6601 / XV6600 (HTC Harrier)

I am trying to set up my 6600 to send and receive pop email from my gmail account, and while I can receive fine, I am unable to send. Gmail specifies that the outbound smtp server needs to be on port 587, yet on the pop outbound server setup on the 6600, there is nowhere to specify port. Any ideas? Or do I need a third party email application.

Thanks
