First one:

This isn't a valid bounce message to begin with: it should have had the
null sender (MAIL FROM: <>).

Second one:

> Return-path: <>
> Envelope-to: [email protected]

Had you used SRS, this convo might have looked something like:

> Return-path: <>
> Envelope-to: [email protected]

Which, after validation at MTA level, you would then have accepted. And
soon as the MTA came in at: RCPT TO: <[email protected]>, you would
have rejected it (for being unsigned).
