iPhone: .Mac mail can not send emails over WiFi - other accounts are fine
____
Cannot Send Mail
The connection to the server "smtp.mac.com" failed
____
This error only happens over WiFi and not when on the edge network.
I configured my .Mac account on the iPhone by choosing ".Mac" and continuing the set up process within the Settings of iPhone. It was not synced from iTunes. There are limited options to edit or configure when you have the iPhone set up a .Mac email account. For example you do not have access to edit smtp settings with a .Mac account.
I have ATTYahoo DSL with the new Airport Extreme (n) base station at home. However this issue also occurs on other WiFi networks i have tested. My MacBook Pro has no issue sending .Mac email over the same WiFi.
MacBook Pro, Mac OS X (10.4.10)
