Odds are, the message was sent as HTML-only, i.e., the message consisted of
a single MIME part with a content type of text/html. When you configure a
list with 'Language= NoHTML', LISTSERV deletes HTML MIME parts only if the
message contains at least two MIME parts and at least one of them has a
content type of text/plain.

In May 2001, I submitted a change request which stated:

        The use of 'Language=NoHTML' in a list configuration should result
        in the rejection of a single part message with the content type of
        'text/html', accompanied by an error message to the sender of the
        message.

for the complete text of my message.

Hey, L-Soft! When are you going to address this issue?
