Dynamic Recipient Verification
Dynamic Recipient Verification (DRV) is a mechanism to validate the recipient of an incoming email with another SMTP
server running downstream. Consider a scenario where you filter emails for multiple domains that are then forwarded to more
than one SMTP server.
Using DRV, Xeams can check if the recipient of an incoming email is valid and will be accepted by the next SMTP
that is supposed to receive the message after it has been filtered by Xeams.
When to use DRV
Consider using DRV if you are using the Regular SMTP Server
to process incoming emails
and you do not want to create a local user in Xeams.
How to use it
- Login as admin to the web interface
- Click SMTP Configuration under Server Configuration
- Click the link for DRV on the left hand side
