Question on how to set attachment rules

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I currently have attachment_rules and attachment_filters settings as:

configset listname attachment_rules <<ENDAAM
text/plain | require
ENDAAM

configset frambors attachment_filters <<ENDAAL
text/plain | allow
/./ | discard
text/html | format
text/enriched | format
ENDAAL

I would like to support PGP signature attachments so that they are not
stripped out.

A typical PGP signature attachment will look like this

Content-Type: application/pgp-signature; name="signature.asc"
Content-Description: OpenPGP digital signature
Content-Disposition: attachment; filename="signature.asc"

Also, I see this line before the first MIME header.
This is an OpenPGP/MIME signed message (RFC 2440 and 3156)

Is there something I can do to allow these through?

Also, in the help configset_attachment_filters verbage, it says something
about signed messages, but I'm not clear if this is on a different topic.

[The keep action
- ---------------
The keep action causes a body part to be passed untouched.  If the body
part has subparts, those also will remain untouched.  For example,
to allow a signed message to be posted without alterations, use the
following rule:

multipart/signed | keep]

Does this help me?

TIA
