/* dconn is the Decnet Connect program. The intention is that
** it will open a decnet socket (stream) and transfer stdin to that
** while everything from the connection goes to that.
**
** sendmail can then use that with an entry like
**
** MDsmtp, P=/usr/lib/mail/dconn, F=msDFMueXLR, S=13, R=24, E=\r\n,
**	A=dconn #130 $h
**
** because there is no $u in the arguments, sendmail will talk smtp to it.
