That is correct. According to the sender, this used to work but does
not now. No changes have been made to the list (AFAIK) and none to
the mailman software.

I asked the user to send mail from Lotus Notes to the listserve and it
does the same thing. Just to you know, the sender has several list
serves he is mailing to. In one case, the mail was delivered (to 19
members), the other was not delivered (to 32 members). I am checking
the configuration of both list serves and conparing them. I will let
you know what I find out.
