AIUI, PBL is supposed to be for dynamic-type IP addresses for
residential service, so if you have business service something seems
off.
What did your ISP say when you asked them about this? I would expect
them to be concerned because giving customers addresses in RBL is
obviously going to get them sorted into giving not-really-ok service and
negative recommendations, if that's what is really going on.

They said they have a spamhaus license, which I'm assuming is for their own
servers, and that they would leverage that to ask a support question, but
they're disclaiming any responsibility.
spamhaus license is a different issue.
These aren't new netblocks for us from them, but it seems awfully weird
that we would be operating on these IPs for 2+ years then all of the sudden
have them listed like they're dialup IPs.
generic/dialup DNS names can help here. If they aren't dynamically
allocated, their DNS records should contain at least string "static".
It's generally advised to use personalized DNS names (reverse and direct)
for mailservers or any hosts supposed to send e-mail.
Note that if you send mail using authentication, you usually don't need
this.
The message I received during the delisting process with spamhaus/PBL for
"MyProvider" was:
Outbound Email policy of MyProvider LLC for this IP range
It is the policy of MyProvider LLC that unauthenticated email sent from
this IP address should be sent out only via the designated outbound mail
server allocated to MyProvider LLC customers. To find the hostname of the
correct mail server to use, customers should consult the original signup
documentation or contact MyProvider LLC Technical Support.
I don't know if that's just a boilerplate message or it actually refers to
the precise reason why my IPs were added to the PBL.
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.
