npub1hwzna5706gkfu7963zctxy0978kfxsva4zf8nq2zx93rtrm4yj8ssag6cs (npub1hwz…g6cs) npub1czlgwwr3d7ywl6fj05p7826avmldz7spjxmsrk2un0luvfkkp60s3887qa (npub1czl…87qa) The vulnerability causes the recipient MTA to wrongly assume the mail came from a user/domain it wasn't actually from, i.e., the mail will pass SPF/DKIM checks at the receiver (which in turn makes the DMARC handler happy).

SMTP Smuggling is *designed* to fool SPF/DKIM checks!
