Thank you for you work on this and for releasing it. I’m also having difficulties with errorlevel. Swithmail seems to frequently not save the logfile, so the workaround above wouldn’t work either.
What is tested for in the errorlevel check? I’ve entered an unknown email address which produces an undeliverable response, but both the CLI and Test function in the GUI report no errors. I’m trying to make a way of resending the email if it isn’t sent, eg email server issue.
