The load on the other server was too high, and this is a simple
way of separating things.

I've got courier calling maildrop, and maildrop calls SA and
filtering. But the problem is, after it's been through maildrop, I want it
sent on to another computer. I'm using postfix for that (see maildrop rule
below), which then forwards to another server. If I can get courier to do
this instead of postfix, I'd be happier, but I couldn't see a way to do it.

Well, yes, but:
a) It will reject e-mail for all new users unless we set up a cron
job to
create home directories. Then it will still reject e-mails for all
new users for eg. the first 15 minustes
b) If we don't have to create home directories, everything is simpler,
and therefore less likely to break. After all, it's not like we're
*using* the home directories, since all mail is forwarded elsewhere
c) It's not elegant :).

Well, that's good to know, and I'll do it that way if I have to,
but I just assumed there must be a better way :). After all, I've
heard of this
separate mail filtering server idea that we're implementing in a few places
before, so I assumed that things would be set up to do this with a bit less
difficulty :).
What would make it really easy is if there was some way to get the
ESMTP output stage to run maildrop :). That would mean that we're not using
courierlocal at all. If anyone knows if that's possible, that would be
wonderful.

Any help is much appreciated
Thanks,
