Siri doesn't want you to have any other friends.
Seriously, though, I have no idea. Maybe some more info on what mail service you are using would be helpful.
Here are some ideas from other posts:

Go into Settings>Mail, Contacts, Calendars>your account>Outgoing mail Server SMTP>Primary Server then turn Server ON and fill in both User Name +Password under Outgoing Mail Server.
This is a very late response I realize but I have the same problem. Emails send and receive fine, then all of a sudden at least once a day my emails get stuck in the outbox and i get the same message as in the original post. I have to power off the phone and then when it turns on again all the emails will send until it happens again, sometimes the same day or for sure again the next.
YOU GOT IT RIGHT
