[rt-users] PGP signed attachments being 'broken'

I'm using RT to manage support for an academic department of 60 staff.
Many staff use PGP/MIME to sign their email[1], which is great.

Unfortunately, mail which passes through RT and is PGP/MIME signed is
'broken':

- - The signature is identified as a normal attachment, as far as I can
  see, and is added to the 'Attachments' section of the ticket display:
this is unhelpful, since if a ticket consists of many email messages and
replies, there will be many signatures appearing here;

- - The outgoing mail, which was originally signed in the MUA, includes
  the signature as an attachment (signature.asc), but the Content
headers (or MIME information) is modified (as compared to the original
message) meaning that the email arriving at its destination is no longer
a valid PGP/MIME message.

Anyone have any hints or ideas about how to handle this?

[I can supply example messages and headers if required, but I won't
clutter the list with them unless they're really needed: my suspicion is
that this is a not uncommon problem, although I haven't found any
helpful discussion in the archives about it.]

Cheers,

Dave.
