why does my mail say this message cannot send
Every time i try to send a email from my mail on my laptop it says
"Error This message could not be sent. It will remain in your Outbox until it can be sent.
This message could not be sent because your account does not have a preferred outgoing mail server. Select an outgoing mail server from the list below." could someone tell me how to fix it?
MacBook Pro, iOS 7.1.1
