Emails received but not sending

[AC Question]

I have a galaxy s4, Ive set up my bt email accounts manually using imap which was recommended as they have a junk folder, emails are coming through fine but I cant send any, they just sit in my outbox. have checked my outgoing smtp server settings from the bt website and they are fine.

Can anyone help me please

Make sure everything in the outgoing server properties screen is correct. Besides the name of the outgoing server and the SSL/port number, also make sure your username and password are correct.
