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
