Phone won't connect to server

[AC Question]

Hi I have just got a S6 phone and have trouble when I try to put my email settings in. It comes up with " Could not Connect to server " or " Authentication failed" I have had a galaxy S2 and S3 and had no problem getting my email to work on them.
Any help would be greatly appreciated, Thanks Rob
