I wonder if this is related to:

Account Set up fails with SMTP error

I tried to update an account and I’m too now getting an error I have submitted a PR here. Used the compiled DLL in my Windows PC and it worked. You can compile my code and use the compiled mailcore2.dll to replace your old one, or you can take the one I have saved on a pretend release on my fork and use that. I’d recommend renaming the old one rather than replacing it, just in case. In Windows, you can find the file to replace at C:\Users\[YOUR_USERNAME]\AppData\Local\Mailspring\app-1.10.5\r…

Could it be that Gmail is also stopping the test email from being sent to email@invalid.com. If so, this could be why mailspring is always reporting a SMTP error

If anyone can try the file I’ve generated a test, that would be great. Just a shot in the dark.
