I have a .mac account so I'm using the smtp.mac.com server. This works fine when I'm using my .mac account on my iPhone.
The problem is that I have Work email pushed to my iPhone. I can't use my server at the office (long story) so I want to send using the smtp.mac.com server.

This did work on my iPhone 1G - but it's not working with the 3G.

Anybody else experience this or have any fixes?

Thanks,

Chris
