I can't send email suddenly following the change of my password(s) (apple & iCloud). Mail was able to connect to the Internet, however iCloud "could not connect to this iCloud IMAP server.

How do I fix my email preferences?

I just changed my passwords and got a new computer. Now I can't send email. Connection status says ok - Mail is able to connect to internet.

Below that across from iCloud & IMAP it says" iCloud could not connect to this ICloud IMAP server" Should I change something here?

Below that is Account name- smtp.mac.com:cbridges...and the note"Trying to log into this SMTP account failed. Verify the username and password are correct." Should I do anything here? Passwords and usernames are correct.

Incoming mail still works!
