Emails have stopped sending using my iCloud account on my MacBook Pro
Hello,
My emails have started to stay in my outbox. After a few minutes Mail tells me that my outgoing mail server is not working. It keeps sending the odd mail but not all. Very strange! My iCloud emails are incoming absolutely fine, and they are sending and receiving fine on my iPhone. It is like a setting has changed somewhere but I cannot figure it out.
If anyone could help me it would be great. I did have a quick search on the community but couldn't find exactly the same problem.
Thankyou.
MacBook Pro 15″, macOS 10.14
