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.

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. You have to be careful when allowing this, because you may configure VPOP3 to be an open-relay, which is a

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).

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…

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…

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.

It occurs if some other software running on the same machine as VPOP3 is using one of the ports that VPOP3 is already using.

Using a Permanent 'Always On' Connection This is the most common connection method. It assumes you are connecting to the Internet via a router which is permanently connected. In this scenario VPOP3 simply needs to connect to the router so setting up VPOP3 is very simple.

What is PostgreSQL?

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

What is PostgreSQL? PostgreSQL is an SQL database engine. VPOP3 and PostgreSQL In VPOP3 2.x, VPOP3 uses a database engine called SQLite for its database needs. SQLite has limited locking facilities, so on busy systems we encountered problems where databases would need very frequent updates, and the lock limitations would cause the updates to take a long time. For this reason we added optional support for PostgreSQL to later versions of VPOP3 2.x.
