You should remove permit_mx_backup.
This feature is intended for ISP-scale users that may not have a
complete list of domains that use their server as a backup MX. In
this case, permit_mx_backup_networks would define the ISP's customer
network space.

I've just tried that, but the mail queue filled up with double-bounce

to sort out my configs, as there's clearly some stuff going on that I don't
understand.
BTW in the meantime, if I add this (where mx2.mydomain.com is our secondary
MX hostname), I take it that would be a good idea:
permit_mx_backup_networks = $mynetworks mx2. mydomain.com
no, these are IP addreses or ranged, not hostnames.
have you added those domains to relay_domains?
To answer your previous question: yes, relay_domains is the list of domains
your server is supposed to provide backup MX for, independently on permit_mx_backup
and permit_mx_backup_networks setting.
or is there a way of replacing address verification (if that's what is
going on) with something better?
