In encoutered this in your message signed that is coming in this way in
the last 3 days. Come to think of it I have received signed messagges
earlier but did not have this problem. I do not add signatures but I
think yours does for outgoing mail. Maybe that is the problem.

As long as you are only using PGP/GPG, the digital signature isn't
messed with since MailScanner adds text after the PGP Sign block.

If you are using a certificate to sign the message, then it does alter
the content since the certificate signs the entire contents of the body
and not just a block of it.
