The IDS/IPS tab lets you set logging and automatic blocking parameters for the IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) component of the SMTP server.

SMTP servers are regularly attacked, both by incoming mail attacks (spam/viruses etc) and relay attacks (by spammers and other malware distributors trying to send mail through them). Because of this, there is a system in VPOP3 which will track attack attempts on the SMTP service and can automat…</description>

        <description>Database files used in VPOP3 2.x

VPOP3 2.x usually uses SQLite 2.8.3 as its database engine. This stores databases in discrete *.db files in the VPOP3\_database directory on the server PC. We do not recommend that you access these databases directly unless you know what you are doing, and we strongly discourage the alteration of data in the databases directly unless technical support request you to.</description>

	*  Groups

Using a list

A list will contain zero or more &#039;members&#039; (usually email addresses) which can be messaged all at once. To send a message to all the members of a list, you will usually send an email to the listname at a valid domain.</description>

        <description>Lua Scripting

Lua is a simple scripting programming language often used for embedding in other applications. VPOP3 uses it to customise behaviour in places where most people will be happy with the default behaviour, but occasionally people will want to do something more complicated. Rather than having lots of extra options to complicate things for most users, we have opted to go for a more flexible scripting facility.</description>

Settings -&gt; Misc Settings -&gt; DNS

The DNS tab lets you specify which DNS servers VPOP3 will use. DNS (Domain Name System) is a system which converts Internet host names (eg www.google.com) into a numeric IP address (eg 1.2.3.4), because all connections on the Internet are actually performed using numeric IP addresses, but it is easier for people to remember names.</description>

Domainkeys

“Domainkeys” is a way of signing a message to show that it comes from the person it claims to come from.

The system is too complex to go into here, but it essentially takes key parts of the message header, as well as the message body and creates a PKI digital signature on it, using a &#039;private key&#039; on your system. The receiving end will find the same…</description>

This script is for the case where your ISP adds a header eg &#039;X-Spam: Yes&#039; to the message header, and you want the VPOP3 spamfilter to quarantine messages with that marker.

        <description>Status Monitor (port 5109) protocol

This page documents the protocol used between VPOP3 and the Status Monitor. It&#039;s not intended for any other purpose, so it&#039;s a bit limited, but in certain cases you may find this useful

Login

Before the Status Monitor receives any updates or can issue commands it must log in using a user&#039;s credentials.</description>

        <description>Virus Scan Filter Scripting

(Added in V6.17)

The VIRUSSCAN.LUA script has a single function FilterResult

This function is called for every virus that a VPOP3-integrated (eg VPOP3 AV or Sophos SAV Interface) detects. The function has the opportunity to &#039;filter&#039; the virus detection so that VPOP3 will act as if the virus was not detected.</description>
