I don't think so.  I just added the hostname to the server /etc/hosts
file and it made no difference.  And the failure is a hang instead of a
useful error message, which I would expect from an active rejection.  I
did run saslauthd with "-d" and found it produced no ouput when I tried
sending mail.  So it seems to me that Postfix smtpd is never
successfully contacting saslauthd.  I did try turning on TLS logging,
but that doesn't seem to help.  I don't *think* the problem is in TLS.

I did not have this before.  I do not believe this feature is useful in
my setup where I want to be able to relay mail remotely (i.e.: Not on
the local net).  I depend on sasl authorization alone for relay access.
