Can't send iCloud mail. "Edit SMTP Server List" is empty.
Something is up with Mail.app's SMTP for my iCloud account.
I can't send email with my main iCloud account.
I have 3 iCloud accounts.
I have 1 Gmail account.
Connection doctor shows one one thing is not like the others. But green lights across the board.
When I look at my accounts under Mail > Preferences > Accounts the available outgoing servers looks good!
But when I select "Edit SMTP Server List..." I see nothing.
I tried signing in/out of iCloud. I know that iCloud accounts don't have any configuration to do. You just put in your username (email address) and password and everything else is set up.
I can send from that account on iOS!
I tried deleting/re-adding my account.
I tried starting up in Safe Mode.
I saw some posts about replacing Accounts.plist which was in Library/Mail/V2 but with Mojave, we're up to V6.
If anyone has specific solutions on what to look at, replace, try, let me know!
