Sometimes, something goes wrong, causing Mail on the Mac to have trouble sending a message. When it does, you may see an error like the one below, encouraging you with a default button to try another configured server. Don’t do it! Always click Try Later. If that still doesn’t work, contact your favorite tech support professional to troubleshoot the problem with the SMTP server associated with the account from which you’re sending. Attempting to send through another SMTP server is a recipe for trouble because various anti-spam checks may fail, causing your message to be filtered as spam or bounced back to you. Worse, if you select a different server and click Try With Selected Server, Mail remembers that choice going forward, so you will have to reset it manually later.

Social Media: If Mail on your Mac throws an error about being unable to send a message, always have it try again later rather than switching to a different server. Otherwise, your messages may look like spam and be blocked.
