--- Comment #2 from Jeremy Harris <[email protected]> --- RFC 6376 defines the trailing semicolon as optional (section 3.2), and not part of the tag-spec. It defines the signature as being evaluated with the value of the b= tag replaced with an null string. The value is part of the entire tag... so I suggest that _if_ the header is ;-terminated, and the b= tag is last in it - it is correct per specification to calculate the signature using "b=;" and those places you mention who are not doing so are out-of-spec. That said - we could change Exim to not add the trailing ; and still be in-spec, and presumably pass those validators. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
