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. If an address is on both the Whitelist and the Blacklist, they will cancel each other out, and the me…</description>

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>

        <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>

Lua is a simple scripting programming language often used for embedding in other applications.

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>

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>

        <description>Incoming SMTP Mail

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.

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>

Anyone can send an email to the ListServer to subscribe to (public) mailing lists, or unsubscribe from mailing lists they are on, or see a list of public mailing lists etc.</description>

        <description>Spam Filter Rules: Comments

The VPOP3 Status screen has two tabs

	*  Server Status
	*  Sessions

Server Status

The Server Status tab is essentially a copy of the VPOP3 Status Monitor information.

	*  Connection Status - this shows the &#039;online&#039; status of VPOP3. If it says idle, it does not mean VPOP3 is not working, or not doing anything, it just means that it is not currently sending or collecting mail from the Internet.</description>
