sendmail is old, has an old and antiquated design.  It is not _mature_.
COBOL is old, but it doesn't mean that it is mature.

Wrong.  Sendmail is used by the big guys because if you install solaris,
hp-ux, or aix, it is already there, pre-installed.  It's like asking, why
use netscape or mozilla on windows, if IE is already there and
pre-installed.  Why even bother?  That's a big question, and unfortunately
only a handful that know of how MTAs really run can actually answer that
question of why you need to junk sendmail over postfix/qmail.

You're right!  Sendmail is used basically because it's installed out of
the box.  It's not a decision of maturity of technology, its a decision
mainly based on a 'why bother' attitude.

Postfix was developed with the support of IBM.  That enough for you?  And
yes, you are right.  For them to be widely used, they must be incorporated
in major linux distros and unix distros as well.

Oh yes as a unix sysadmin it must be clear to you which technology works
better than others. That's what you're being paid for!  In the search for
such technology it should be plainly obvious why sendmail is old and
antiquated technology, which should be retired.

You should read the performance benchmarks of postfix and qmail, and read
why sendmail is not used by major mail hubs.
