Overview

The eMail Server Relay Check Tool is a simple security tool designed for testing email servers for signs of misconfiguration.

You can gain access to the eMail Server Relay Check page by selecting

 NSTWUI > Network > email > eMail Server Relay Check

The tool checks for the following:

 SMTP banner - reverse DNS mismatch
 Open Relay
 Bounce Messages or Non-Delivery Reports (NRS's)
 Listings on DNS-based Realtime Blacklists
 

Optionally, it will also perform a quick port scan for open NETBIOS ports.

Configuration

In order for the tool to work correctly, you will need to change the variable $email_address to your own email address. This is located on line 30 of the file /usr/share/relaycheck/cgi-bin/relaycheck.pl

$email_address='change_this@change_this.whatever';
