Yup.  It's definitely not there.  This has me completely perplexed.
You seem to be doing everything correctly, and all of the right things
are appearing in the sendmail.cf file, but the fault is definitely
occurring.

All I can conclude is that there is some trivial boo-boo somewhere
that will have you slapping your forehead and shouting "D'Oh!" in the
approved Homer-Simpson-esque style.  It's going to be something on the
level of you're not using the sendmail binary you think you are, or
it's not reading /etc/mail/sendmail.cf.  Have you sanity checked
/etc/mail/mailer.conf ?  Does anything untoward appear in
/var/log/maillog ? How about the maillog entries when you restart the
MTA?

Can you try this: run sendmail in address test mode:

    % /usr/sbin/sendmail -bt

and check the output of dumping the mailer definitions:

    > =M

(ie. make sure that the local mailer definition being used by sendmail
is actually the same as in /etc/mail/sendmail.cf) Also try:

    > /parse david at skytracker.ca

which should give you Parse1 and parse lines like so:

    Parse1           returns: $# local $: david
    parse            returns: $# local $: david

indicating that your sendmail will use the local mailer to do the
final delivery.

	Cheers,
