I just updated my iPhone 4G to iOS5.1.1
The main issue (which I never had before the update) is that I can no longer SEND email to any address that is not on my own server.
I host many sites and have many emails set up, 4 of which are on my iPhone. I can send between those email accounts but not to an external account such as an AOL or Yahoo account.
Puzzling! I spoke with AT&T and Apple tech support but they don't get it.
During the OS update the default AT&T SMTP server (cwmx.com) was simply removed. I tried using it but it no longer works.
So how would I be able to SEND an email to someone other than myself???
