Hi @sunnypatell, as with #6944, the only change I made was to set attack vector to network instead of adjacent.

same situation as #6944 @shelbyc. sisimai parses RFC 5322 bounce emails, so the malicious input literally arrives over SMTP/network. VulDB's AV:A was clearly wrong here. appreciate the correction.
