        <description>How to install the VPOP3 Status Monitor on other PCs

The VPOP3 status monitor icon is run by a separate program from VPOP3, which communicates with VPOP3 using TCP/IP. This means that this program can be installed on any PC which can connect to the VPOP3 computer using TCP/IP (on port 5109 by default).</description>

        <description>How to Backup VPOP3

By default VPOP3 v3 and later will automatically perform a daily backup of the database into a file called DBBACK-x.DMP, where the backup file rotates on a weekly basis (DBBACK-0.DMP is Sunday&#039;s backup, DBBACK-1.DMP is Monday&#039;s backup, etc).</description>

        <description>PostgreSQL Replication

PostgreSQL 9.1 (used in VPOP3 5 and later) supports replication from a &#039;Master&#039; to a &#039;Slave&#039; database server. This can be used with VPOP3 for having a near-realtime backup of your settings &amp; 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…</description>

        <description>How To Upgrade VPOP3

Note: if you are upgrading to VPOP3 version 5 or later from version 4 or earlier, please see How To Upgrade VPOP3 to version 5

Upgrading VPOP3 is a straightforward process. Download VPOP3 from our web site and ideally back up your current installation just in case something goes wrong. Then simply run the installer that you downloaded and install it over the top of your existing VPOP3. All your settings and mail will be preserved.</description>

To set up an iPhone to access VPOP3&#039;s mail, you first of all need to configure VPOP3 to allow access by remote users (unless you will only be using the iPhone in the office, connected via WiFi to the office LAN).

        <description>Socket Error 10503 - No More Data

Error 10503 means that the connection between VPOP3 and a remote computer (normally your ISP) was dropped at an unexpected time. This is different from the error 10054 in that this is a controlled line drop.

One way this can happen is if the ISP&#039;s POP3 server uses an obsolete standard which allows it to drop the connection if a POP3 &#039;LIST&#039; command is performed on an empty mailbox. The current standard requires that the connection is not dropped until the clien…</description>

To delete an outgoing message, go into the VPOP3 settings, then go to the &#039;Users&#039; page. At the top of the page will be a line saying Outgoing Message Queue.

        <description>&quot;Too many logins&quot; error message

VPOP3 version 4 and later have a limit on the number of concurrent logins which can be received for a single user or from a single IP address. This is to prevent a single user from bringing the server down.

The current default limits are 20 per user, or 1000 per IP address (to allow multiple people sharing a NAT IP address)</description>

        <description>Use Download Rules for incoming POP3 message filtering

If you have VPOP3 retrieving messages from a POP3 account on an ISP, then you can use Download Rules to do basic filtering on incoming messages. 
(If you have incoming SMTP, then use SMTP Rules instead)

Download rules cannot perform all mail filtering tasks. For more features,</description>

        <description>VPOP3 is using a lot of disk space

If VPOP3 is using a lot of disk space, the problem is usually that there is lots of data there, so it has to use the disk space.

Message Storage

In VPOP3 version 5 and later, all users&#039; messages are stored in the database, so they will occupy space in the VPOP3\pgsql\data folder.</description>

        <description>VPOP3 Not Starting Properly

If VPOP3 is not starting properly, then the first thing to check is whether the database server is starting. In VPOP3 v3 and later, VPOP3 uses a PostgreSQL Database server for data storage, so if the database server is not running, VPOP3 will not be able to start properly. In this case, the VPOP3.EXE process may appear in Task Manager, but it won&#039;t respond to anything, or it may appear in Task Manager and then stop after a short period.</description>
