[Mimedefang] Using relay_is_blacklisted() or Sendmail dnsbl feature ?

Adding this line to sendmail.mc seemed to improve things a lot:
define(`confBIND_OPTS', `WorkAroundBrokenAAAA')dnl
Now Sendmail 8.12.8 responds promptly. I'm unsure if this is
really the fault of Sendmail, and it's funny that there doesn't
seem to be such a problem with DNS blacklist responses on our
servers running Redhat 9 or AIX 4.3, but only on Redhat ES 2.1.
I understand that using Sendmail's dnsbl blacklist feature may
be more efficient than using Mimedefang's relay_is_blacklisted()
function, so I guess that'll be my choice.
