        <description>How to create an SSL Certificate

VPOP3 Enterprise supports SSL certificates for encrypted sessions.

The basic mechanism to create an SSL certificate is that you have to generate a CSR (Certificate Signing Request) then send that to a CA (Certificate Authority) who will sign your certificate and give you the certificate back.</description>

If you get this error appearing when messages are sent to VPOP3, either in a bounce message, or in the VPOP3 status monitor, it means that the VPOP3 computer filter is taking more than the allowed amount of time (usually 60 seconds).</description>

        <description>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&#039; 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 …</description>

        <description>VPOP3 Database Size

The VPOP3 directory is stored in the VPOP3\pgsql\data folder and subfolders.

If you are concerned about the size of the VPOP3 database, there are several factors which may make the database larger than you would expect:

	*  The VPOP3 database contains a lot more information than just messages in mailboxes. This can include settings, outgoing messages, historical logging information, statistical information for the spamfilter, information about archived messages, etc. Also,…</description>

If there is an extremely large number of messages (eg hundreds of thousands) in the VPOP3 OutQueue, then it may take a very long time for VPOP3 v5 and later to start as it check the message database tables for consistency during initialisation.</description>

After installing VPOP3, you will need to get into the VPOP3 settings. The easiest way of doing this is to find the VPOP3 Status Monitor in the Windows task tray. 



Right-click this icon, and choose &#039;VPOP3 Settings&#039;. (If that doesn&#039;t work, see this article to troubleshoot Status Monitor problems). Alternatively, on the VPOP3 PC, you can go to Start</description>

Most people are familiar with mail headers such as From:, To:, Subject: etc. but there are many more which most people never see.

        <description>Repairing corrupted database

With PostgreSQL (as with most high-end databases) the database system will automatically recover after power failures etc, if it can. If it can&#039;t then there is no manual &#039;repair&#039; function, because the data cannot totally be recovered (or it would automatically have been recovered).</description>

        <description>Seeing where a message came from

Sometimes you need to check to see where a message really came from. The &#039;From:&#039; email address is easily forged, so that cannot be relied upon.

The first thing you have to do is to get the full message headers. These may look daunting, but are very useful for problem diagnosis.</description>

        <description>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&#039;t know who that user is. This can cause a problem if unauthorised users try to send mail through…</description>

Spam filter companies use “spamtraps” to catch samples of spam for analysis so filters can be updated. We do this here as well.

Most types of spam are already caught by our spam traps, however sometimes people get lots of spam which gets through the filter because their particular type of spam does not currently get sent to our spam traps.</description>

There are two ways that VPOP3 can be configured to connect to the Internet. Which one you use depends on the service provided by your ISP.

Using a Permanent &#039;Always On&#039; 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.</description>

VPOP3 uses the PostgreSQL database server for most of its data storage.

Normally this will not require any special maintenance, because it will manage itself.

To do any special database maintenance you will need to close down VPOP3 first, because PostgreSQL needs exclusive access to the database to perform any operations such as decreasing the size of database files. Note that these operations may take some time! There are some PostgreSQL utility programs in the VPOP3\pgs…</description>

VPOP3 will normally send an error message to the Main Administrator every time it encounters an error. We recommend you leave it like this in most cases - if an error message occurs repeatedly, then it usually means there&#039;s an underlying problem which needs resolving rather than ignoring.</description>

In VPOP3 Enterprise v7.0 a facility for full-text-search on message content was added. Because the full-text-search indexes can be quite big, this facility is optional.

For several reasons, the full-text-search is stored in a separate PostgreSQL database. This means that it is not backed up with your standard backups. After a restore, the full-text-search index can be rebuilt from the raw message content.</description>

VPOP3 can easily handle mail for several incoming domains.

Exactly how you do it depends on the exact situation.

If the domains are aliases of each other, for instance, you have &#039;mycompany.com&#039; and &#039;mycompany.org&#039;, both of which are the same, so each address at mycompany.com also exists at mycompany.org, and the emails go to the same people regardless of which domain is used, then you simply configure the domains in the ma…</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>

If the PostgreSQL server won&#039;t start at all, because its transaction logs are damaged, you will probably need to recreate the database store totally.

This is not an error message, but we are listing it here because it confuses some people.

VPOP3 sends a &#039;Transmission Receipt&#039; when a message is sent out, and it contains a header asking for the receipt. The default configuration is that it will send the transmission receipt if the sender asks for a read receipt.</description>

Telnet

VPOP3 v8.x uses PostgreSQL 10 as its database engine, which is the latest supported 32 bit version of PostgreSQL. Later versions of PostgreSQL are 64-bit only, which means we cannot use them while continuing to support 32 bit versions of Windows.</description>

        <description>Upgrading VPOP3 to version 9.x from v7 or v8

VPOP3 v9 and later requires a 64 bit version of Windows 8.1 or later 

VPOP3 v9.x uses PostgreSQL 18 as its database engine. This can only easily be upgraded from PostgreSQL 9.3 or later, which means it must be an upgrade of VPOP3 v7 or later. If you are using an earlier version of VPOP3, then upgrade it to v8.7 first, then upgrade to v9 or later</description>

        <description>VPOP3 Deleting messages as &#039;old&#039; messages

If VPOP3 says &#039;deleting old message&#039; in the status window activity log that means that it has seen the unique ID of that message before, longer ago than the time specified for VPOP3 to leave messages on the server, so it thinks that the message is an old message, and so deletes it.</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>
