Right, I wasn't sure if it would send mail to all of them or not. I had
only tested, so far, the case where this host is the only MX for
$domain. But there doesn't seem to be a way to get only the low-number
MX for a given domain...?

$self_hostname will only exist for the domain of the lowest MX host, not
for any $domain that has an low-numbered MX pointing here. The whole
point is to avoid having to configure ~100 files (even if they're just
symlinks) to accomodate a bunch of MX records whose mail should all be
handled the same way.
