Text/html is allowed.  I even added his address to the list
administrators.  The only logging I get is when I set his moderation

Depending on what is meant by "nothing", I've seen something like this  
happen another way.  Some clients will create a multipart/alternative  
message with a text/plain alternate and a text/html alternate.  But  
these clients will just put a note in the text/plain part that says  
roughly, "read the HTML part".

So with normal stripping of the text/html alternative all that comes  
through is a text/plain message that says "read the other part".  This  
naturally confuses list members, although I consider mailman's  
behavior absolutely correct.  The originating client is lying when it  
claims that it's produced a multipart/alternative message.

And naturally I concur with what I've snipped of your message,  
encouraging people to send only text/plain email.

Anyway, the OP should have the user cc the list administrator with  
their next posting attempt.  That way, you can examine the structure  
of the message that got submitted.
