With bind 8.2.2-P5 & sendmail 8.10.1, map_rewrite drops subdomain

[Dan Harkless]

Howdy.  We recently upgraded our primary mail and DNS server, speed3, a
Solaris 2.5 box, to bind 8.2.2-P5 and sendmail 8.10.1.  Now we can't send
mail from boxes in our subdomain to boxes in our primary domain.  If I'm on
shell1.sa.speed.net and send a mail to someone at speed.net, sendmail 8.10.1 on
speed3 incorrectly rejects the mail with:

 501 5.1.8 <me at shell1.sa.speed.net>... Domain of sender address\
  me at shell1.speed.net does not exist

As you can see, the subdomain, "sa.", is incorrectly being discarded by
sendmail 8.10.1 when checking that the sender's domain name exists.  I've
done a lot of looking, and I can't tell if this is due to a bind bug, a bind 
misconfiguration, a sendmail bug, or a sendmail misconfiguration.

We were previously running Sun's provided bind v4 and sendmail 8.8.5 and we
didn't have this problem.  speed3 does have sa.speed.net in a separate
(non-$INCLUDEd) db file, which isn't the way the "DNS and BIND" book seems
to recommend handling non-delegated subdomains, but putting the sa.speed.net
machines in the main db.speed.net file didn't seem to help.

The only sendmail configuration file that the sa.speed.net domain shows up
in is relay-domains.  There is currently no masquerading as "speed.net" set
up on speed3.

Here's the output when sending mail to speed3 with sendmail 8.10.1 in debug
mode (not very illuminating -- doesn't show why map_rewrite drops the
"sa."):
