How to fix email settings when the port and TLS/SSL are not working?

I have changed port, checked "use TLS/SSL, and authentication- Password" (instructions given by server.) I click "save" however, settings returns to the wrong settings. Can't send anything out. Do receive messages from this server.

with no details my best advise—


For problem accounts the go to way to sort things out is to delete the account(s) from the Mail.app, then add it back.

Remove email accounts in Mail on Mac

Remove email accounts in Mail on Mac - Apple Support


Add email accounts in Mail on Mac - Apple Support

Add email accounts in Mail on Mac - Apple Support


Note—

IMAP accounts stay on the server, so no local loss, when you re-sync

POP accounts download and remove from the server—therefor save your inbox/sent box if you want them

“On My Mac" is just that, local folders you created and moved mail into. So no loss
