IANAL, nor particularly versed in RFCs, but it looks to me like RFC
2046 and neighbors (in several parts) lay out the recommendations for
MIME messages. The debian "unsubscribe sig" does appear on non-MIME
messages (non-rfc2046?) on my MUA (mutt), but are correctly not shown
in MIME encoded ones since they fall into the epilogue section. I
can't find anything relevant on "unencapsulated rfc822"; can you
provide any references?
