yes, they are explicitly telling you to use mailserver outside of this
range. If you have own mailserver, you should dedicate IP address for
it, one that won't be added to PBL by your ISP.

So you believe these IPs would have been added to the PBL by our ISP? Do
you know how that might have been done?
It is possible that your ISP listed their IP ranges there.
IP address can get to PBL and similar listing by DNS, whois data, and spam
detected from those can also help.
If your ISP told you to send mail through other mailservers, while you have
own mailserver, perhaps you should discuss this with your ISP.
ISP should be able to contact Spamhaus to delist those ranges, or provide
you with other range.
I'm trying to understand why or how we would have been added to the PBL
when nothing was changed. It was the entirety of our netblocks, not even
just the IPs we're currently using.
Try providing IP address/range?
