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.text/html2025-08-14T09:24:55+00:00Anonymous (anonymous@undisclosed.example.com)Lua SMTP Relay Control

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:text/html2018-11-14T10:45:49+00:00Anonymous (anonymous@undisclosed.example.com)Mappings

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 'aliases'text/html2018-11-14T10:45:49+00:00Anonymous (anonymous@undisclosed.example.com)Message Monitoring

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.

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.text/html2021-11-29T12:06:24+00:00Anonymous (anonymous@undisclosed.example.com)Password Lengths
