SMTP Open Relay

Jump to solution

Our OpSec team is complaining that our deployment of ESRS is running as an open relay.  The relevant link is from Tenable.

https://www.tenable.com/plugins/nessus/10167

It NTMail3 Arbitrary Mail Relay.  I don't see any misconfiguration in the console GUI.  Is there any way of preventing the security scan from showing this as an open relay?

Please check the knowledge base article

500525 : ESRS VE: ESRS being reported as open SMTP relay (CVE-1999-0512) https://support.emc.com/kb/500525

A small configuration change will prevent the SMTP service from acting as a relay.
