Which is the right question? Postfix sensibly performs message inspection on input. Postfix only performs content downgrade (to 7bit, or to SMTP line length limits) on output, as some channels don't need the downgrade. Therefore, if you want to sign mail, you MUST hand Postfix email that does not need to be downgraded. One approach is to sign in post-queue content filters, and to force content downgrades when delivering into the content filter, so that the filter sees "normalized" email. Better yet, send email that requires no downgrading. -- Viktor.
