this is almost certainly your signature - this was discussed way back on
the list. It is alleged that there is a bug in perl itself which means
that the signature adding bit of MailScanner can end up changing the
line terminations throughout the whole message body. This obviously
affects digital signatures and the like. As far as I know it has never
been fixed. I'm having difficulty tracking down the relevant threads on
this list but it has been discussed a couple of times.
Either you have secure digital signatures, OR you add a corporate sig
onto each message. You can't have both.
Of course you can add a rule-set for adding/not adding the corporate sig.
