Outgoing Message Scripting Every time VPOP3 adds a message to the Outgoing mail queue, it runs a script called outmessage.lua. Scripts are stored as files in the VPOP3 directory in VPOP3 v6.6 and earlier, or managed through the Settings -> Scripts page in VPOP3 v6.7 and later.

Lua SMTP Relay Control

Anonymous (anonymous@undisclosed.example.com) — 2025-08-14T09:24:55+00:00

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:

Mail Connectors -> Mail Senders -> SMTP Direct

Anonymous (anonymous@undisclosed.example.com) — 2018-11-14T10:45:49+00:00

Mail Connectors -> Mail Senders -> SMTP Direct VPOP3 can be configured to send mail directly to the recipient's mail server (or the recipient'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. Attempts to use SMTP Direct sending on a dial-up/ADSL/Cable/FTTC/etc connection may be problematic since the receiving mail server may think you a home user who has been …

POP3 Mail Collection

POP3 Mail Collection POP3 Mail Collection is when VPOP3 will collect mail from an external POP3 mailbox - for instance, from an Internet Provider. POP3 General This page tells VPOP3 how to collect mail. * POP3 Server Address - this is the name (or IP address) of the POP3 server from which you want VPOP3 to collect mail

ListServer Commands

Anonymous (anonymous@undisclosed.example.com) — 2018-11-14T10:45:49+00:00

ListServer Commands The ListServer is an automated process in VPOP3 which manages mailing lists. People can send commands to the ListServer to perform various functions remotely. Whether these commands are allowed, and exactly how they work depends on the particular mailing list's settings.

Autoresponder

Anonymous (anonymous@undisclosed.example.com) — 2018-11-14T10:45:49+00:00

Autoresponder An autoresponder is a way of automatically replying to messages as they arrive in a user's mailbox. In VPOP3, an incoming message must arrive in a user'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 'Assistant'…

End() End() This function is called by VPOP3 when the SMTP service session ends SMTP Server Lua Scripting The SMTP Server Lua Script is called SMTPSVR.LUA and can be edited from the Settings -> 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.

Signature Script

DMARC Reporter Script

Anonymous (anonymous@undisclosed.example.com) — 2023-11-12T09:51:40+00:00

DMARC Reporter Script (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's DMARC configuration is incorrect as that can cause errors sending the reports or cause messages to be 'stuck' in VPOP3's Outqueue. These problems won't cause any lasting damage, but may be inconvenient or annoying, so you can alter the behaviour using Lua scripting

Error Handling Scripting

Anonymous (anonymous@undisclosed.example.com) — 2023-11-20T10:18:01+00:00

Error Handling Scripting For most error messages that VPOP3 generates, it allows control of error messages, eg to limit the frequency of error messages if they would be generated repeatedly. These limits are set in Settings -> Admin Settings -> Message Control. However, if you want more granular control, you can use Lua scripting for more fine-grained control

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.

LAN Forwarding LAN Forwarding is a feature of VPOP3 where it can send messages to another mail server using SMTP.

Route incoming POP3 mail by parsing message headers

Route incoming POP3 mail by parsing message headers This routing method is generally used if you have a catch-all or 'multi-catch' 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.
