In many ways, configuring Outlook 2010 is a similar to configuring Outlook 2007. The biggest difference you are likely to notice is the new “Ribbon” interface, in place of the traditional menu bar (File, Edit, View, etc.)

        <description>Sending mail from different email addresses or domains

VPOP3 does not (by default) place any restrictions on which email addresses or domains you can send mail from. However, there may be external restrictions on which email addresses/domains you can send from. For instance, if you send mail through your ISP&#039;s mail server, they may only allow you to send mail from specific addresses, or the domain you send mail from may have a sender policy defined, such as</description>

VPOP3 Enterprise 2.6 and later supports SSL/STARTTLS encrypted sessions to VPOP3 itself. So, the email client or web browser will encrypt the data passed to VPOP3 so it cannot be intercepted.

This requires an SSL Certificate to be created for VPOP3.</description>

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>

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>

VPOP3 can be configured to send mail directly to the recipient&#039;s mail server (or the recipient&#039;s mail service provider). Usually this is only used if you have a high-end business class Internet connection - such as a leased line, or your mail server is co-located in a data centre.

        <description>POP3 Protocol

POP3 is the most basic email protocol for collecting mail which is in common use.

Almost all email client programs (such as Microsoft Outlook &amp; Outlook Express, Mozilla Thunderbird, etc) can collect mail using POP3.

With POP3, mail is usually downloaded by the email client and stored on the user&#039;s local PC. It is then deleted from the mail server, so the only copy is on the user&#039;s PC. Any mail folders etc are all managed on the user&#039;s PC.</description>

If an error occurs whilst running this program, VPOP3 will create a &#039;Database Backup Failed&#039; error message to the administrator.</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>

        <description>Exceptions

An exception happens if VPOP3 encounters a problem it did not expect. In some cases it can recover automatically, but in other cases that isn&#039;t possible.

Common causes

VPOP3 2.6 and earlier

In VPOP3 2.6 and earlier it was quite common for there to be database corruption problems with the SQLite database which was used in those versions.</description>

        <description>SMTP error &#039;Invalid HELO name&#039;

When sending mail you may get an error from the remote SMTP server saying something like &#039;Invalid HELO name&#039;

This happens if the host name configured in VPOP3 does not look like a valid Internet host name (e.g. &#039;mail.domain.com&#039;). Some SMTP servers don&#039;t bother checking this value because it has no authentication value at all, but a few do check that it looks correct.</description>

For VPOP3 to monitor outbound messages it needs to be able to work out that the message is FROM: a user whose mail should be monitored. To do this it has to examine the FROM: address in the message header.</description>

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>

LDAP Server Conflict

When you run VPOP3 on a server edition of Windows you may receive an error saying

LDAP server not started - couldn&#039;t bind socket port 389 (10048)

This error happens because VPOP3 contains an LDAP (Lightweight Directory Access Protocol) server for its global address book functionality, and the Windows 2000/2003 &#039;Active Directory Service&#039; also uses LDAP as its mechanism. These two services are conflicting.</description>

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

        <description>Problems with installing PostgreSQL during VPOP3 Installation

Sometimes people have problems with the PostgreSQL installation part of the VPOP3 installation. Below are some things to look at.

	*  Check that &#039;Local System&#039; (or &#039;System&#039;) has full access to the VPOP3 installation directory</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>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>Training the VPOP3 Spam Filter

The VPOP3 spam filter has a couple of mechanisms which can be used to &#039;train&#039; it to distinguish between spam and not-spam.

Bayesian Filter

The Bayesian filter this looks at words in messages sent and received and their probabilities of being contained in spam and not-spam, and works out an overall probability of the message being spam or not-spam based on the combination of those probabilities.</description>

Telnet

One of the most basic, and useful, tools for troubleshooting email systems is a Telnet client. 

Installing Telnet Client

Unfortunately, since Windows XP, Microsoft do not install the Telnet client into Windows by default, so you may need to install the Telnet client yourself.</description>

This routing method is generally used if you have a catch-all or &#039;multi-catch&#039; 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.</description>
