<blush> I have a would-be subscriber sending from a site that adds a
"Sender: postmaster@......" header to every message in addition to
the user's "From:"  My initial " don't do that !!!"  resulted in a
quote from RFC822 ( sec 4.4 -> 4.4.4 ) ( definitions of FROM/SENDER )
The original reject from LISTSERV follows - How SHOULD I advise this
user ???                       - mike
