The rmail.c distributed with sendmail 5.61 specifies a -odq option to
sendmail, which asks sendmail to queue the mail for later delivery and
not deliver it immediately.  Is there a significant reason for this,
or can I just change it to -odb for normal background delivery?

This is considered a plus in rmail because you will tend to get a lot of
rmail processes all at once after a UUCP neighbor calls up and dumps on
you.  Having each one queue rather than deliver in background tends to
trim the CPU spike.  If Ox and OX worked reliably, this wouldn't be nec'y.

Yeah, I noticed this too.  We checked with Keith a couple weeks ago.
The `-odq' thing was a mistake and can be changed to do immediate
delivery; although I'd prefer staggering the jobs using `-odi' rather
than `-odb'.

Ok, so if -odb is a plus, wouldn't -odi be even better? With -odb you have to
wait until the hourly queue run before your mail is delivered. With -odi, the
mail is delivered immediately but uuxqt is held up until delivery is complete.
That solves your load average problem. It's the same technique normally used
by rnews, but sendmail takes only a tiny fraction of the time.
