Hello,
You will find bellow parts of my script that create a virtual alias map from on
premise AD. You’ll have to work on transforming the output yourself
(/usr/local/bin/get_exchg_aliases.awk in my script).
And you’ll have to tune AD_FILTRE to suit your needs.

My only concern is if there is as an example a recipient that has literally
2K email addresses with LDAP/AD, which associates with how much inbound
mail wont that slow down delivery a good amount, and potentially create a
lot of overhead?

No, my advice is to replace the "list" with live LDAP queries to AD,
on demand during each SMTP transaction.
Thanks Viktor.
To confirm, I'm creating the list of valid emails to accept and then
forward and if not in that list reject.
My question would be, will postfix send off a process to query every so
often in order to build the multiple lists, or as each mail is about to be
delivered?

Thanks for the response Wietse, I have tried this but many servers won't
correctly allow the verification (its turned off) we have even added rules
to allow our IP's get the verification, but we end up delivering the
message only to then have it rejected which defeats the purpose.
