Thanks for figuring this out. The same solution worked for me. Here are the steps I took in case it helps clarify for anyone else:


1. Change the settings to Mail->Settings...->Composing->Check Spelling->Never

2. Send a test email to confirm it sends.

3. Change setting from Never back to When I Click Send.

4. Send a test email with a spelling error to confirm it checks & sends.

I'm pretty sure the problem only started after the 15.4 update.


In case it helps anyone helping: The Mail Connection Doctor window shows the IMAP & SMTP "Connection and login to server succeeded" for my FastMail account. I have checked that I can save a Draft in Apple Mail, open the FastMail Mac app, and send it from there.
