Can't send emails from one of my accounts on iPhone 7 IOS12.3.1
I have two accounts on my iPhone 7 (IOS 12.3.1). The one which is set to the default sends and receives no problem, the other receives only and comes up with an error messaging saying the Outgoing Server does not allow relaying.
I have tried changing the default and still get the same message.
I have also checked the Outgoing Server information and it is the same as I use on my MacBook Pro which works fine.
Any ideas??
iPhone 7, iOS 12
