I receive emails on my iPhone 4S fine. But, when I try to send emails I get an error message saying it can't find the server. I added another of my accounts to my iPhone, still get the same error message.
You have a problem with SMTP server settings.
This can be found in Outgoing Mail Server under the email account you set up on your iphone
Most likely you need authentication to be ticked in there.
i shut it down, waited until the apple appeared, then waited until it started up again. works fine now. before, i didn't have the garbage pail to delete messages. that is back now.
