Help – mail is failing in test.

Nevermind – the interface said it had failed, but I got both the test emails. Weird!

Hello handguns! Thanks for using Postman! I would love to know what the error was when you sent the email? Can you post the error message?

The same here, with a browser message:

The page at (…) says:

The server returned an unexpected and invalid result:

The messages sent by Contact Form 7 get delivered as well.

Any ideas?

@mmagnani Looks like the plugin choked on your test recipient address. It couldn’t have been as simple as “webmaster@mydomain” ? Were there any special characters, or anything unusual?
