Those are generally due only to communications issue at the mail - host ship’s company . In my experience , and that of Macworld readers , it ’s much more vulgar that the extroverted mail waiter requires troubleshooting .

Apple ’s Mail app for iOS , iPadOS , and macOS reveals errors that occur when a link to an incoming or extroverted mail server ca n’t be made . For instance , you might see an error in Io that read , “ The connecter to the outgoing server ‘ waiter name ’ failed .
