Hi, we are running sendmail 8.14.2 together with dkim-milter 2.3.2. Now if there is a message with multiple addresses in the "To:" or "Cc:" header and the MUA formats them as follows:
1st example To: [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED],<CR><LF> <HT>[EMAIL PROTECTED] 2nd example To: [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED],<CR><LF> <SPACE>[EMAIL PROTECTED] sendmail is reformating the whole thing as follows: To: [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED],<CR><LF> <SPACE><SPACE><SPACE><SPACE><SPACE><SPACE><SPACE><SPACE>[EMAIL PROTECTED] Note: <HT> is a tab hex 09 <SPACE> is a space hex 20 This reformating is done after the dkim-milter has calculated and inserted the signature, which leads to a failure upon messages verification. I reported this as a bug to the sendmail developers, but I got as answer that it is not a bug in sendmail and that there will be no fix to this: --------8<------------- This is "established"/well-known behavior for sendmail 8. I think it is a "bug" (omission/oversight) in DKIM (it is amazing that the DKIM authors didn't take this behavior into account, but added provisions for many other "layout" changes). White space (in "formatted fields") that doesn't change the semantics should not influence a signature. --------8<------------- I know that running a sandwich configuration with 2 sendmail damons (rx -> fwd -> tx+dkim) could help. So the first sendmail daemon does all the reformatting and forwards the messages to a second daemon which then is running the dkim-milter. This is not a real fix and hits the performance and introduces unneeded complications. Is there anything that could be done in dikm-milter to avoid/solve this problem?
