Help configuring Postfix Recipient Verification

**NethServer Version: 7.3.1611
Module: nethserver-email
I have been trying to find a way to enable Postfix recipient verification. We have all of our SAAS platform realy email through our Nethserver and are working on cleaning up address in our database. At this time we send about 200,000 email a day which equates to a lot of bad email address while we perform cleanup on our end. Postfix recipient verification would also help stop the issue by not sending to addresses that do not exist. I have spent a lot of time trying to figure out how to configure this on Nethserver since there is custom configuration but to no avail. Any help or suggestions would be highly appreciated.

AFAIK address verification is enabled by default and it can’t be disabled.

Could you please describe what you need and what you did?
I mean: commands, configuration files, examples, etc.

For details on NethServer address verification, see this old issue about moving the address db from disk to ram:
