Looks like there’s a _lot_ of broken systems out there then 🙂

I see mails with `X-Auto-Response-Suppress: All` (from exhange)

Some just have:

```plaintext
Content-Type: multipart/report; report-type=delivery-status;
	boundary="110e4b6c-159b-4262-b2ca-cbe359515e6a"

```

as content type (and no other identifying headers)

QMail just sends a reject mail from `From: MAILER-DAEMON@somedomain` or `From: mailer-daemon@somedomain`.

Another one: `X-QQ-HolidayReply: true`

(I setup a sieve filter to block mailer-daemon & postmaster locally which cuts down 99% of these btw)
