Integrate ASSP server with Exchange 2019 Server Cluster

Job ID: 30772971

Budget: $30 – $250 USD

I have a small exchange 2019 cluster (2 exchange servers, 2 domain controllers and 1 witness server).
I have also set a virtual server running ASSP.

The inbound spam scanning and relaying is working perfectly. But I'd like to fully integrate exchange into it.
3 things basically need to happen.

1. The server needs to be setup to allow exchange to route outbound mail through the ASSP server (making the ASSP server the default outbound mail server).
2. If possible I would love to integrate assp with LDAP on exchange so that it can verify local domains and email addresses before passing mail on to email account's that don't exist
3. I would also want to change ASSP to deliver detected spam to the spam/junk folder in exchange (rule based I assume).

I would need the person who set's this up to do so over anydesk or teamviewer since we need to participate to make sure nothing breaks and brings client's down.

I also need someone with experience in this. If you don't have experience setting this up before. Please don't offer to do the work since this is a requirement.
