Is there any way to configure Courier to *not* generate DSNs for this kind of situation?

No. This is how SMTP is supposed to work.

You will have to either stop using a secondary MX, or reconfigure your spam filter to drop unwanted mail, instead of rejecting it.

That's fine, but how does one set up a backup MX without a secondary MX?

a backup MX is not really needed anymore, everyone on the internet that is running a mailserver should have a good enough connection to recieve mail in a timely fashion. Even if your mailserver is not reachable for over a day the sending mailserver will queue it up for typically many days before you will start losing mail.
