my case, it was a /24 that was blocked (mixture of dialup, dynamic dsl,

Having proper rDNS and if possible suballocating dialup / dhcp and static ip pools would be a good idea, so admins can tell these apart when they are applying ACLs.

This was repeated a couple times, apparently. It might have been better
if I had specifically requested unblocking of just the one IP in there
that actually runs a mailserver - it likely would have stayed unblocked.

That too is a good idea.
