You reach this tab by going to Settings --&gt; Spam Filter -&gt; General, and then choose the General tab.

The Spamfilter script has various settings that can be changed to alter the behaviour of the spamfilter. These are defined in the script, so may change with different versions of the script. The settings are currently:</description>

This article only applies to VPOP3 v4 and earlier

A VPOP3 autoresponder can contain special text strings to create special behaviour, in addition to plain text as part of the response.

There are three types of &#039;command&#039;

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>

If you have an incoming SMTP mail feed, then the mail server sending mail to you will connect to your VPOP3 computer to send the mail. The mail connection is controlled by the sending computer.

If you have a permanent Internet connection with a static IP address, the usual way of having incoming SMTP is to configure your</description>

To view the LAN Forwarding Queue Status, go to Settings -&gt; Local Mail -&gt; LAN Forwarding -&gt; Queue Status

The LAN Forwarding Queue shows the messages which VPOP3 has currently got queued to be sent to another mail server on your network using SMTP. 



The LAN Forwarding Queue status page shows a simple list of the messages waiting to be sent. The four columns in the table show:</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>

        <description>Lua SMTP Relay Control

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>Mappings

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>

        <description>Message Monitoring

Message monitoring in VPOP3 will tell VPOP3 to send a copy of all the outgoing, internal and/or incoming mail from/to specified users to be sent to another specified user.

In the current versions of VPOP3, all monitored messages are sent to the same user (or list), you cannot specify different recipients for different monitored users. (This may be something that is added/enhanced in the future)</description>

        <description>Route incoming POP3 mail by parsing message headers

This routing method is generally used if you have a catch-all or &#039;multi-catch&#039; mailbox with your Internet provider. With this method, VPOP3 will look at the To/Cc and other fields in the message headers to try to work out who the message is for. If the recipient is not listed in the headers (eg for BCCd mail) it may not be able to automatically detect who the message is for.</description>

If you want more complex signatures on outgoing emails, rather than the static text/HTML you can define within VPOP3, then you can use a simple Lua script to define the signature.

The Lua script is stored in a file called signature.lua</description>

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

        <description>Spamfilter White/Blacklists

This lets you set whitelists &amp; blacklists for the spam filter.

There are four lists you can manage. The Whitelist Addresses &amp; Blacklist Addresses lists let you specify sender email addresses to check. With the default rule weights, if a sender&#039;s address is on the Whitelist, it will be allowed through the spam filter, and if it is on the Blacklist it will be blocked.
