--- Comment #5 from Guillaume Outters <guillaume-e...@outters.eu> --- Created attachment 1096 --> https://bugs.exim.org/attachment.cgi?id=1096&action=edit full rewrite of pdkim_headcat In addition to having this bug, pdkim_headcat seemed to have complexified over time, so maybe it's time to make a (working!) rewrite of the function. With it running on my server I created valid DKIM signatures: - in my nominal case (the signature ending 1 character before the EOL, the semicolon correctly gets the last place on the line) - by shifting everything (introducing a space before the b=), thus having the signature take the full last line, and the semicolon correctly appear on the start of a new, padded line So this corrects the "disappearing last char" problem, on the b= ending semicolon. Note that this applies only on the full signature, not on the one with an empty b=; used to compute the signature: in both our cases (my exim server and exim-dev's one), the bh= always gets on a new line, so b= always stars at position 49, so there is no chance that the b=; gets split around the semicolon: h=abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz0123456789abcde abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz; bh=abcdefghijklmnopqrstuvwxyz0123456789; b=; For this to be tested, we could play with the h=, removing some headers to let the bh= and the b= get a place without starting a new line: h=abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz0123456789abcde abcdefghijklmnopqrstuvwxyz012345; bh=abcdefghijklmnopqrstuvwxyz0123456789; b= ; Now *this* would get interesting, because it would confirm (or dismiss) the undeterministic "could insert a linebreak" comment. -- 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/ ##
