This is not something new in LISTSERV, but there may have been a change
in the behavior of the gateway they use with Microsoft Mail.  Depending
on which gateway they are using, it probably allows control over whether
the mail headers are passed through with the message.  Some MS Mail
clients allow control over this as well (StripGatewayHeaders in MSMAIL.INI
with the Windows client).  But if headers are turned off, the ability to
track down problems is compromised and much useful information about the
message is lost.
 
Putting Loopcheck=NoBody in the list header turns off the checking for
headers in the mail body, but think carefully before you do that, as
you may end up with a mail loop.  Certainly don't do it if you use
Safe=No.
