        <description>SMTP Server -&gt; IDS/IPS

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>

Download rules are a facility in VPOP3 where it can look at message summary information before downloading a message from an ISP POP3 mailbox (they do not work on incoming SMTP messages - use SMTP Rules for that)

        <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>

	*  Distribution Lists

	*  ODBC Mailing Lists
	*  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>

The Quarantine Viewer lets you see messages which have been quarantined by the VPOP3 Spam Filter. As an administrator you can see quarantined messages for any user, and release them if appropriate. If you release a message, it will be sent into the original recipient&#039;s Inbox, not into your Inbox.</description>

In VPOP3 a &#039;group&#039; is mainly an administrative feature. If you only wish to have a list of email addresses to send messages to under one address, you should use the &#039;List&#039; feature instead. The main function of Groups is to let you set certain user attributes for a whole group of users at once.</description>

VPOP3 Host Name

The VPOP3 Host Name is used by VPOP3 when it is telling other mail software what it is called. For instance, when it connects to another SMTP server it will send the host name as the parameter for the HELO or EHLO command, and when an SMTP client connects to VPOP3, it announces its name in the welcome banner as required by the SMTP standard.</description>

        <description>Autoresponder

An autoresponder is a way of automatically replying to messages as they arrive in a user&#039;s mailbox.

In VPOP3, an incoming message must arrive in a user&#039;s mailbox for the autoresponder to trigger. If you use forwards, assistants, mappings, etc to divert a message before it arrives in the mailbox, the autoresponder will never trigger. If you want to use an autoresponder, but not keep the original message, then make sure the message arrives in the mailbox (eg by using an &#039;Assistant&#039;…</description>

The Edit User -&gt; Message Rules tab can be used to create/edit rules which are processed when messages arrive in a User&#039;s mailbox.

They can be used to copy messages, mark them as read, delete them, etc

VPOP3 will process Message Rules in the order they appear in the list. If you want to change the order of the rules, you can drag &amp; drop them into the correct order. Usually when VPOP3 has processed a rule, it will go on to check further rules, but you can use the</description>

Message Store

The Delay while moving messages setting tells VPOP3 how quickly to import messages into the new database structure if it was upgraded from version 2.x or earlier. Usually this is OK to be left as it is, but if there is some special requirement to import the messages more quickly, you can decrease this number, but that will increase the load on the server.</description>

        <description>Lua SMTP MX Control

Every time VPOP3 is going to send messages using direct MX sending, it runs a script called mxout.lua which can be created/edited in Settings -&gt; Scripts (or in the VPOP3 directory in VPOP3 v6.6 or earlier).

Global Variables

Starting with v8.8, the following global variables are defined:</description>

Every time VPOP3 is going to send messages via SMTP Relay, it runs a script called relayout.lua in the VPOP3 directory.

Global Variables

This script may have global variables, depending on your version of VPOP3.

In VPOP3 3.0.0L and later, there are two read-only global variables set at the start of the script:</description>

        <description>SMTP Server Lua Scripting

The SMTP Server Lua Script is called SMTPSVR.LUA and can be edited from the Settings -&gt; Scripts page in the VPOP3 settings. This script is called whenever an instance of the VPOP3 SMTP server is launched - ie whenever someone opens a connection to port 25 on the VPOP3 server to send it a message, whether from a local user or an incoming SMTP message.</description>

In VPOP3, Mappings are a way of explicitly linking an email address to a user or list. They can also be used to indicate that an email address is remote, even though it would otherwise appear to be a local email address.

In other email servers, a similar feature may be called &#039;aliases&#039;</description>

In extremely rare cases, the mail folder message counts in the database may get out of step with the actual stored messages.

VPOP3 can be configured to send mail directly to the recipient&#039;s mail server (or the recipient&#039;s mail service provider). Usually this is only used if you have a high-end business class Internet connection - such as a leased line, or your mail server is co-located in a data centre.

        <description>VPOP3 Webmail Help

Webmail is a way of accessing your mail using a normal web browser. It is designed to be close in functionality to a &#039;normal&#039; email client, so should be straightforward to use.

There are four lists you can manage. The Whitelist Addresses &amp; Blacklist Addresses lists let you specify sender email addresses to check.
