What does the following mean ?
 
    Node FRECP11 says that LISTSERV is an unknown user but
                 file PEERS NAMES says the opposite :-
 
Batch SMTP transaction log follows:
 
> 220 FRECP11.BITNET Columbia MAILER X1.25 BSMTP service ready.
> 050 HELO TUBVM.CS.TU-BERLIN.DE
> 250 FRECP11.BITNET Hello TUBVM.CS.TU-BERLIN.DE
> 050 TICK 9219
> 250 9219 ... that's the ticket.
> 050 MAIL FROM:<[log in to unmask]>
> 250 <[log in to unmask]>... sender OK.
> 050 RCPT TO:<[log in to unmask]>
> 250 <[log in to unmask]>... recipient OK.
> 050 DATA
