I haven't read rfc822 in a while, but I seem to recall that you can't
have ``just'' an HTML message.  If you want to send and HTML message,
then you need to send a multipart/mixed message with one part being
the HTML version and one part being the text version (see the message
from mailman for an example).  Even if this is not a requirement, a
lot of spam filters will flag messages that only have an HTML part. 
Perhaps the lack of having a multipart/mixed MIME wrapped around the
HTML is causing it to match ``the cwe-lug mailing list's content
filtering rules and was prevented from being forwarded on to the list
membership.''

The real question is why would Thunderbird send a malformed message? 
I see Ed is using Thunderbird 1.5.  Did this problem start after the
upgrade?  Regardless, the simplest workaround is to send plain text
messages:

  Edit->Account Settings->Your Account->Composition & Addressing
  deselect ``Compose messages in HTML format''

No one want all those extra tags and bytes anyway.
