the bsmtp router which comes as part of urep supports "mail from:<>".

history (1983) - originally only "trusted mailers/routers" or "local
user agents" were suppose to be able to send mail to/through a BSMTP
mailer/router/gateway.  i.e., BSMTP was originally NOT to be a user
protocol. BSMTP routers were suppose to have been written for the
different systems on bitnet. it never happened. however many users
were willing to wrap their own BSTMP so they could use one of the
bitnet gateways (i.e., psuvax1). it was impractical (and unwise)
to register each such user. instead a router/gateway is suppose to
check BSMTP mail from non trusted users to make sure they aren't
lieing about who the mail is from. many of the gateways on bitnet
simply don't do this. the code supplied with urep does. trusted
mailers must be listed in a file "DOMAINS" which also specifies
the domain naming tree.
