Hi and welcome back everybody;

I have a sendmail install on one of my machines that does nothing but
forward all mail to a central mail hub (mail-hub.fastlax.com);
sendmail-8.9.3 on FreeBSD-3.3-STABLE.

in sendmail.cf:
---------------
Fw/etc/sendmail.cw

# "Smart" relay host (may be null)
DSmail-hub.fastlax.com

# Who I masquerade as (null for no masquerade)
DMfastlax.com

#Who gets all local email traffic
DHmail-hub.$m

everything seems to work 'OK' i.e mail is being sent and received nothing
gets lost but in /var/log/maillog I see error:
Sendmail[11233] to=danielb@fastlax.com, ... relay=mail-hub.fastlax.com.,
stat=deferred: Name server: mail-hub.fastlax.com: host name lookup failure

This can't be because the deferred mail has been sent and show-up in my
mailbox and the host mail-hub.fastlax.com exists! nslookup ans telnet to
port 25.

Why do I keep getting this error messages.

Sendmail sucks-up sooo much administrative time it is not funny!
Thanks

Dan
