In article <166@academ.UUCP>,  I write:
# The SunOS3.4 sendmail does not support MX records. It also does not support
# the $[ $] cannonicalization convention. These two things alone make it 
# difficult to use the SunOS 3.4 sendmail on an internet Sun that has to
# deal with lots of mail. I would hope the SunOS 4.0 sendmail can do this 
# stuff.

Following this posting, I received mail from Sun agreeing that 3.4 does
not support MX records. However, the writer called the statement about
$[ $] "an outright lie". And asked that I post a "correction". I replied
that I would explain the statement and so I am. 

---------------------- BEGIN EXPLAINATION -----------------------------
The claim that $[ $] does not work is based on tests I ran. Does the
3.4OS Sendmail use the YP to satisfy this resolution or does it ask
NAMED? If it uses YP, it takes MUCH MUCH longer than asking NAMED 
directly to resolve the address. In fact I could not get it to work, but
I was unwilling to wait more than five or six minutes. If it asks NAMED 
directly, something is seriously wrong since 4.3MXsendmail resolves in
seconds. That is the basis for the "does not support" statement. Perhaps
I should say "It also takes greater than 5 or six minutes in the tests
I ran to do the $[ $] cannonicaliztion. Using the same tests and the
same configuration file, it takes seconds with MX_sendmail." That is not
an "outright lie".
-------------------- END OF EXPLAINATION -------------------------------

He was also good enough to supply me with a new sendmail that does
use MX records. For this, I thank him. If Sun supports all their
customers like this, they are to be congratulated.
