Vodacom's email does not work - Vodamail

Hi,

I called the call Vodacom centre today as we're unable to send emails from our phones using our Vodamail email accounts.

When we are at home using our WiFi (ADSL) we cannot send emails but when we are away from home on Edge or 3G then the emails send.

Now the call centre said I should change my SMTP setting every time I arrive home so that I can send my emails from home.

HOW YOU EVER HEARD SOMETHING SO RIDICULOUS??? Imagine Google or Hotmail or Yahoo telling their customers that?

Does anyone have a solution for this? Secured SMTP settings or different setting?

Thx
