        <description>How do I get support?

You can get support for our software products in several ways.

By telephone

	*  You can purchase an annual priority support contract. The cost depends on your current VPOP3 licence, and costs 50% of the licence price per year (with a minimum of £100) per software licence (+VAT if applicable) . This entitles you to software upgrades, remote support and telephone support during UK office hours and priority email support where we aim to respond to your email within 3 hours …</description>

If you installed a new router on your network and left it at the default settings, you may find that VPOP3 doesn&#039;t seem to work afterwards. This is because it may be that the new router allocates new IP addresses on your network.</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>When sending mail, VPOP3 adds &#039;PRVS=...&#039; to the sender address

This is because VPOP3 version 5 and later support BATV. BATV helps to eliminate &#039;backscatter spam&#039;, where someone else sends spam pretending to be from you, and then you receive all the bounce messages from those messages. BATV encodes the sender address in a special way so that VPOP3 can detect that a bounce message is in response to a message that you actually sent.</description>

        <description>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.</description>

Refuse SMTP Connections from

This setting should be rarely needed, and should be normally left blank. It is here for historic purposes.

If you put some text in this box, then VPOP3 will refuse any SMTP connections from clients whose &#039;HELO&#039;/&#039;EHLO&#039; command data contains the text specified here as a substring. Eg, if this setting is set to &#039;.myisp.com&#039;, then VPOP3 would refuse SMTP connections from any client which sends the c…</description>

(Note - no version of VPOP3 will run on “Windows 10 S”)

Version 9.0 or later

VPOP3 version 9.0 or later requires Windows 8.1/2012R2 later. It needs a 64 bit version of Windows.

Version 8.0 or later

VPOP3 version 8.0 or later requires Windows 7/2008R2 SP1 or later. It should run on both 32 bit and 64 bit Windows.</description>

        <description>Socket Error 10054 - The virtual circuit was reset by the remote end

Error 10054 means that the connection between VPOP3 and a remote computer (eg the ISP or another computer on your LAN) was disconnected by something outside of VPOP3.

This is often caused by anti-virus software or Internet security/firewall on the VPOP3 machine but it could be any of a number of things. Any software or hardware that is sitting between VPOP3 and the ISP could be the root cause.</description>

        <description>Full Text Search

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>

If you want to have a VPOP3 server and Exchange Server using the same email domain, then you need to ensure that Exchange does not think it is &#039;authoritative&#039; for the domain in question.

See &lt;http://support.microsoft.com/Default.aspx?kbid=321721&gt; for details of how to do this in Exchange 2000 and 2003 (a similar process may be used in later versions of Exchange - contact your Microsoft Support technician if you need more help).</description>

        <description>Message Downloads Not Completing

The normal reason for message downloads not completing is that a third-party antivirus program is scanning the messages and getting stuck at some point.

We recommend that the first thing you do is to temporarily disable the email scanning part of any antivirus program or Internet Security software on the VPOP3 computer (other than those integrated fully with VPOP3 - i.e. &#039;avast! for VPOP3&#039; or &#039;Sophos SAV Interface&#039;). Usually that will solve the problem.</description>

        <description>Outlook not able to connect to VPOP3 Enterprise v6.8 when using SSL/TLS

In VPOP3 6.8 SSL v2 is disabled by default (it is considered to be insecure). SSL v3 was released in 1996 and SSL v2 was deprecated because of the well known security flaws.

However, it seems that Microsoft Outlook (up to at least Outlook 2010) will not connect to VPOP3 using SSL if VPOP3&#039;s SSL v2 is disabled.</description>

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. Rather than having lots of extra options to complicate things for most users, we have opted to go for a more flexible scripting facility.</description>

VPOP3 Versions 2.1.7 and later have a built-in spam filter system which supports a simple script language optimised for content- and spam-filtering of email messages.

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>

        <description>Out of Disk Space When Sending Mail

The first thing you should do is check that there is enough free disk space on the disk where VPOP3 is installed. VPOP3 requires a certain amount of free space before it will allow new messages to be sent, so the disk might not be totally full, but VPOP3 will still report that there is insufficient disk space when you try to send a new message. This buffer zone is designed to help prevent the disk totally filling up, which can cause lots of bigger problems!</description>

        <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>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 &#039;spoofing&#039; 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&#039;t come from an authorised IP address.</description>

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>

(Also applies to version 1.x)

To move VPOP3 to a new PC you should go through the following steps:

	*  Copy the VPOP3 files
		*  Copy the VPOP3 directory and subdirectories from the old PC to the new PC. (If you are moving to Windows Vista/2008/7/2012/8 or later, do NOT copy the files to a &#039;Program Files&#039; folder on the new PC.
