At one time, the only Mail Transfer Agent (MTA) software easily available
|
|
was sendmail(8). As a result of this, most Mail User Agents (MUAs) such
|
|
as mail(1) had the path and calling conventions expected by sendmail(8)
|
|
compiled in.
|
|
|
|
Times have changed, however. On a modern NetBSD system, the administra-
|
|
tor may wish to use one of several available MTAs.
|
|
|
|
It would be difficult to modify all MUA software typically available on a
|
|
system, so most of the authors of alternative MTAs have written their
|
|
front end message submission programs so that they use the same calling
|
|
conventions as sendmail(8) and may be put into place instead of
|
|
sendmail(8) in /usr/sbin/sendmail.
