TNEF strangeness

[Dean Manners]

On the topic of TNEF, I have noticed a strange qwerk with my setup. When the
Rcpt To: contains a realname/quotes the message is tinkered with by MS-TNEF
and the message (if HTML) is converted to plain text.  When the Rcpt To:
doesn't contain a realname/quotes the message is delivered as it was sent.

When using the external TNEF expander the message content is attached in a
txt file; eg msg-29134-17091.txt.
When using the internal TNEF expander the message is not attached, but still
converted to plain text.

Trimmed headers of two html test messages are included below; the first with
a realname/quotes in the Rcpt To that was converted to plain text, the
second without realname/quotes that delivered as it was sent.

# /usr/bin/tnef --version
tnef 1.2.3
# MailScanner --version
This is Perl version 5.008004 (5.8.4)
This is MailScanner version 4.57.6


Whats interesting is, looking at the SpamAssassin header, the first message
is converted to plain text prior to going to SA.  Any ideas on how/why this
happens ?
