>Eric, do you have any interest in teaching LISTSERV to read BSMTP? > >Bill Or, alternatively, teaching MAILER to DISTRIBUTE. Before you laugh, if you are on node A, sending to one user on each of B, C, and D: A-----B-----C------D (nothing fancy) You get three separate BSMTP files, one each for B, C, and D. But, if MAILER knew the topology (like LISTSERV does) it could generate a single BSMTP file with RCPT TO: each of B/C/D, and forward the file to 'B'. It then does its local delivery, and forwards on the 'C/D' remainder to C, and so forth. In other words, you could do a LISTSERV 'distribute' using BSMTP if you knew how to split the recipients, and where to send the packets.
