   I'm not quite old enough to predate Berkeley in my computer use, but   
   generally, I wasn't in systems that used Berkeley-style Unix, with the   
   exception that mbox format was a Berkeley invention that non-Berkeley   
   systems tended to use.   
      
   Non-Berkeley Unix systems that were compatible with Sys V Rel 4 like   
   Unixware used mailsurr, a file one was expected to edit for email   
   rewriting rules. sendmail was not native to these environments.   
      
   I have no clue what genuine SVR4 in house at AT&T used for email.   
      
   My first Unix compatible was Xenix, which was actually decent. What did   
   we use for email transport? I cannot recall.
