Yep that was my idea, but this can't work and will never work, when the local mailer modifies the email. The local mailer cannot send an email before signing. So the workflow is actually correct. > Is there a reason that the local mailer is used in your case when > sending mail to remote machines? I sent an email to myself, thus the email never had to leave the server. ;-) This is why the local mailer was used. But this whole thing revealed that DKIM and the 9 flag in the local mailer are incompatible. Not only for me signing emails, but for anyone. If your mail server signs an email, but my local mailer changes it, then this will screw up your DKIM signature. My local mailer is always used to deliver any email to my user and thus inbox, so allowing my local mailer to modify an email is a no-no. The question now is, does my disabling of that flag have any drawbacks? Is such a conversion really needed in this day and age? Cheers, K. C.
