Look, your the list owner, so, that means you make the rules for your
list.  What you can do as a solution to the problem below is to manually
subscribe people the way you want them to be subscribed, ie with name and
address and all.

I am running a list which it had been decided before the development of
the list that we wanted to have anonymous e-mail addresses, but real
names.  So I set the headers on my list to follow that pattern.  If I
remember correctly, that would be shortHDR, but if you set your list to
fullHDR, I thionk you will get what you are looking for.

For the record, I do not think it would be prudent to not allow
subscribers from a particular sight due to lack of courtesy by others at
that site unless yoiu can reasonably say that the problem is widesperead
from a number of people from a sight.

Maybe there could be a ban list in a future addition of listserv (as
opposed to a filter list) which would automatically bounce messages from
the addresses of your choosing.  The list owner can decipher who sent the
messsage and simply decide that people who refuse to play by the rules of
the list, (which they agreed to by joining the list) should not be allowed
to post to the list.  Just an idea.  The practicality oif this is not
within my knowledge, so if what I have suggested is beyond doing, please
ignore it.

BTW, I got a great chuckle from the copied message below.
