Which at a guess means he was posting in HTML only, and your list is
set to filter HTML. If that is the case, it is strongly recommended
that you teach your member to set his mail client to post in plain
text (with or without HTML).
I admit that part of this recommendation is due to a strong preference
for plain text formats on my part (in agreement with most of the
people who provide good advice on this list). However, you should
also consider that from the point of view of the Mailman software HTML
mail is *very* complex (it is very hard to parse because many widely
used mail clients produce non-standard HTML, and even standard HTML
may contain many constructs that Mailman cannot possibly deal with
because they're private extensions), and therefore many features of
Mailman's processing become unavailable to you, or worse, silently
corrupt messages in transit.
In short, allowing HTML posts on your mailing lists is asking for
trouble. I don't guarantee you'll get it, but lots of people allowing
HTML have received a visit from Mr. Murphy.
