Test Email Backend (locmem) accepts email with blank recipients

[joelhaasnoot@…]

The email backend used in the testing frameworks accepts all messages and does no checking about the content of the email. Most importantly, if the recipient is blank, the email is accepted anyway, while most if not all mail servers will reject those emails. Several other checks might be useful too, but could be split up into a seperate (testing) backend.

This idea is a bit vague, and it looks more like a feature request than a bug.

As is, I'm not convinced it's useful, and I don't know how we can get a consensus on a list of useful checks. A patch could help kickstart a discussion.

I don't think email message validation is appropriate in the locmem backend. Your application should not be relying the STMP server throwing errors to validate recipients and your testcase shouldn't either. If you want to validate the recipients in your testcase you can pull them off the message and assert that they are correct. If you need the email backend to raise an exception for a testcase it's simple to patch/mock that behavior with available mocking libraries.

I agree 100% with what mlavin writes above. Thus, I'm marking this ticket wontfix.

joelhaasnoot: if there's an actual real-world bug you're running into, please feel free to reopen this ticket with more information. If there's something actually broken with Django's testing framework we'll fix it, but emulating an SMTP server isn't exactly within scope.

Thanks!
