This may not be important in your case, but IIRC the above solution will
also hold local mail until the next queue run.  An alternative is to
configure the SMTP mailer to be 'expensive' -- sendmail will then queue
external mail but deliver local stuff immediately.  You might also need to
convince sendmail not to do DNS lookups when it queues messages.

I unfortunately can't remember the exact details (and the machine with this
setup is not accessible from here...).  You should be able to find all this
on www.sendmail.org or the FreeBSD mail archives though.

HTH,
