How To Setup VPOP3 Service Security

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

How To Setup VPOP3 Service Security VPOP3 can be configured to restrict access to its various services depending on the client computer's IP address. This is useful if you want to allow access from only certain IP addresses (eg within your LAN) and prevent access from other IP addresses (eg the Internet).

SMTP Server -> IDS/IPS The IDS/IPS tab lets you set logging and automatic blocking parameters for the IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) component of the SMTP server. SMTP servers are regularly attacked, both by incoming mail attacks (spam/viruses etc) and relay attacks (by spammers and other malware distributors trying to send mail through them). Because of this, there is a system in VPOP3 which will track attack attempts on the SMTP service and can automat…

We installed a new router and now nothing works If you installed a new router on your network and left it at the default settings, you may find that VPOP3 doesn't seem to work afterwards. This is because it may be that the new router allocates new IP addresses on your network.

SMTP Server Lua Scripting

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.

Dynamic IP Address

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

Dynamic IP Address VPOP3 needs to run on a computer with a static (fixed) IP address on the 'local network'. This does not mean that it will not work with ISPs that dynamically assign IP addresses! A computer which has both a LAN adapter AND a dial-up adapter will have two IP addresses: one for the

550 5.7.1 Relaying not allowed! Bad sender IP address This SMTP error message means that the computer which is sending the message is not permitted to send outgoing messages based on the VPOP3 SMTP Service's Access Restrictions. This is probably because someone is trying to send messages from outside your local network, and you have not configured VPOP3 to allow this.

Accepting Incoming SMTP through a router

Accepting Incoming SMTP through a router If your ISP is providing you with an SMTP mail feed (incoming SMTP) and you have VPOP3 connecting to the ISP through a router then you will probably need to modify the router configuration to allow this. Most routers' default configuration will only allow outbound connections (ie connections from the local network out to the Internet). If you need to accept incoming SMTP mail, then you need to tell the router to allow inbound connections on port 25 for …

Sender Policy Framework / SPF

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

Sender Policy Framework / SPF SPF is a system used to tell mail servers which IP addresses can send mail from which domains. It is designed to reduce 'spoofing' of email addresses. For instance, if you receive an email message from your bank, your mail software can check that it came from an IP address authorised to send mail from your bank, and treat the message with suspicion if it didn't come from an authorised IP address.

How To Allow Mail Relay Through VPOP3

Anonymous (anonymous@undisclosed.example.com) — 2025-05-21T07:57:18+00:00

How To Allow Mail Relay Through VPOP3 If you are allowing remote access into VPOP3 to collect mail then you may also want those remote users to be able to send their outgoing mail through VPOP3 as well. This is more complex than allowing users to collect mail, because, by default, SMTP connections are not authenticated. This means that when someone tries to send a message through VPOP3, VPOP3 doesn't know who that user is. This can cause a problem if unauthorised users try to send mail through…

PostgreSQL Replication PostgreSQL 9.1 (used in VPOP3 5 and later) supports replication from a 'Master' to a 'Slave' database server. This can be used with VPOP3 for having a near-realtime backup of your settings & messages. To use the replication, you need to have a file share which is accessible from both PCs. The thing to watch out for is that the PostgreSQL services may be running as a different user from the currently logged in user, so make sure that the user(s) which the PostgreSQL servi…
