Hi all, Was doing some DKIM maintenance on one of my domains, and noticed one of the systems I use can include a z tag in the signature.
> “z” Tag: A vertical bar-separated (i.e., | ) list of header fields present > when the message was signed. This includes the names of the header fields and > their values. For example: z=From:ad...@example.come|To:j...@example.com| > Subject:test%20message|Date:Date:August%2026,%202011%205:30:02%20PM%20-0700 While almost nobody reads message headers to see the signature, I can see how it can be useful to see if a header was modified in transit. However, how practical/useful/needed is it in real life, and more importantly, is there any harm in testing its use? Cheers, Faisal _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
