What are the correct SMTP settings when using the Telstra 3G network on a mobile phone tethered to laptop

Last Modified: 2013-12-09
I have an HTC Touch HD windows mobile 6.1 phone and I am tethering it to my Laptop for general internet connection. running vista and outlook 2007. The phone is on the Telstra 3G network and I when I try to send mail out it wont allow relaying with the SMTP server. I have tried the SMTP server of Telstra of mail.bigpong.com but I still get outgoing mail still will not go out and I get the relaying message. Does anyone know the right way to send mail out of outlook on the laptop over the Telstra 3G network?

Just call Telstra 3G network and ask if they also require SMTP authentication to be set for sending mails out.

The problem is a little deeper than this "solution".  Feel a little ripped signing up for this answer.

The problem has more to do with Telstra (and other ISP's) blocking port 25 on outbound 3G connections.  There are a lot of forums and users with this problem.  Sorry...no fix though.  Whirlpool has a few forum threads re iPhones that are related though.
