Umm.. because the Sendmail 8.13.3 tree has this:
(from cf/README):
----
If DAEMON_OPTIONS is not used, then the default is
DAEMON_OPTIONS(`Port=smtp, Name=MTA')
DAEMON_OPTIONS(`Port=587, Name=MSA, M=E')
----
from doc/op/op.me:
That is, one way to specify a message submission agent (MSA) that
always requires authentication is:
.(b
O DaemonPortOptions=Name=MSA, Port=587, M=Ea
.)b
Hmm.. no default 'a' to require authentication by default.
That would probably explain why you actually have to work to set it up.
