        <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>

        <description>Send Admin Message

It is possible for administrator users to send a bulk email message to an entire group or list.

To begin composing an email, go to the Administration Settings -&gt; Users page, and click Send Admin Message. 

This should then open a window, which allows you to specify various options.</description>

        <description>User Routing Script

If there is a &lt;username&gt;/user_redirect.lua script, this Lua script can override VPOP3&#039;s message routing options. You can edit this either in the Settings -&gt; Scripts page in the settings, or via the &#039;Routing&#039; tab in the user&#039;s settings in the VPOP3 administration console. This script affects how VPOP3 will handle how messages</description>

For scripting to alter the whole autoresponder definition and set in the VPOP3 settings rather than embedded in an autoresponder itself, see Autoresponder Global Scripting

In an autoresponder, you can create a Lua script by surrounding it with &lt;lua&gt; &amp; &lt;/lua&gt; tags, eg</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>

(from VPOP3 v8.6 onwards)

This script lets you customise how VPOP3 sends DMARC reports to the sending domain. This can be useful in case the sending domain&#039;s DMARC configuration is incorrect as that can cause errors sending the reports or cause messages to be &#039;stuck&#039; in VPOP3&#039;s Outqueue. These problems won&#039;t cause any lasting damage, but may be inconvenient or annoying, so you can alter the behaviour using Lua scripting</description>
