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';
(this documentation is currently under development)
