        <description>How To Setup VPOP3 Service Security

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>

The SMTP Server Lua Script is called SMTPSVR.LUA and can be edited from the Settings -&gt; Scripts page in the VPOP3 settings. This script is called whenever an instance of the VPOP3 SMTP server is launched - ie whenever someone opens a connection to port 25 on the VPOP3 server to send it a message, whether from a local user or an incoming SMTP message.</description>

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&#039;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</description>

If the VPOP3 spam filter appears not to be working at all, the first thing to do is to look at the message headers of an incoming message to see if the spam filter is being run at all.

        <description>Using a Mobile Phone with VPOP3

Many people want to use a mobile phone to send/receive their email nowadays. This is usually easy to do with VPOP3.

The recommended way is to have the phone connect directly to VPOP3 for sending/receiving email. To do this, you need to do three things:</description>

when trying to access VPOP3, then this means that the relevant server&#039;s IP Access Restrictions defined in VPOP3 do not allow access from your client computer.</description>

VPOP3 can easily handle mail for several incoming domains.

Exactly how you do it depends on the exact situation.

All domains are &#039;aliases&#039;

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>

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>

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>

Every time VPOP3 is going to send messages via SMTP Relay, it runs a script called relayout.lua in the VPOP3 directory.

Global Variables

This script may have global variables, depending on your version of VPOP3.

In VPOP3 3.0.0L and later, there are two read-only global variables set at the start of the script:</description>

An autoresponder is a way of automatically replying to messages as they arrive in a user&#039;s mailbox.

In VPOP3, an incoming message must arrive in a user&#039;s mailbox for the autoresponder to trigger. If you use forwards, assistants, mappings, etc to divert a message before it arrives in the mailbox, the autoresponder will never trigger. If you want to use an autoresponder, but not keep the original message, then make sure the message arrives in the mailbox (eg by using an &#039;Assistant&#039;…</description>

        <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>

“Webmail” is a term used to describe an email client which is accessed through a web page rather than as a standalone program.

Some well known services which offer webmail are services such as Hotmail, Yahoo, Gmail etc.

All versions of VPOP3 have a Webmail service included as standard.</description>

The POP3 standard requires that POP3 mailboxes have an &#039;exclusive lock&#039; on them when they are in use. This means that only one POP3 client can access the mailbox at once.

This normally happens because you have told VPOP3 to Leave Messages On Server (on the Mail Connectors -&gt; Mail Collectors -&gt; (name) -&gt; POP3 General tab). If you do this, VPOP3 will leave messages on the ISP&#039;s mail server for several days, and remember that it has already downloaded them. Then, the next time it connects it will see that there are some messages waiting, but it may find that it has already downloaded them, so it won&#039;t download them again.</description>

        <description>VPOP3 - SMTP Client Problem

These errors occur whilst VPOP3 is communicating with your ISP&#039;s SMTP mail server to send your mail.

If the message text is:
Error with SMTP Client (XXXX (YY))
The server connection was closed unexpectedly 
Then this means that the the connection between VPOP3 and your ISP&#039;s SMTP mail server was closed when VPOP3 did not expect it to be. This can be caused by the network connection failing or a bug in the ISP&#039;s mail server which drops the connection in abnormal circ…</description>

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>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>

        <description>IMAP4 Mail Protocol

IMAP4 (Internet Mail Access Protocol version 4) is a more advanced protocol than POP3. With IMAP4 your mail is stored and manipulated on the mail server.

So, if you move a message from one folder to the other, the message is moved on the server. If you send a message, your mail client will (usually) put a copy into your &#039;Sent Items&#039; folder. If you delete a message, it is deleted from the server, and so on.</description>

If you see this error message when you are sending messages, then it means that VPOP3 has detected too many simultaneous connections from your IP address.

This would usually happen if the sender is another mail server as they can make many simultaneous connections when there are lots of messages to send. The error code that VPOP3 gives means that the sender should try sending the messages later, so it should be possible to e…</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 can filter attachments in several ways.

The most general is to use the Settings -&gt; Attachment Processing -&gt; Filtering tab as described below.

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>

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>

If you are wanting to use any of VPOP3&#039;s advanced features (such as mailing lists, message monitoring, wildcard aliases etc) because you are LAN forwarding to a less capable server, then you will usually need to have VPOP3 do all its normal message routing functions initially, then, as the final stage have it forward the messages on to the other server.</description>

        <description>Using VPOP3 Spam Filtering with LAN Forwarding

When using the VPOP3 Spam filter with LAN forwarding you need to be aware a bit of how it works. The spam filter will only quarantine messages which are going to a VPOP3 user. This is because that user needs to be able to log into VPOP3 to be able to view their quarantined messages.</description>

        <description>How To Move VPOP3 Version 2 to a New PC

(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. Recent versions of Windows have special protection for those folders, which is not compatible with VPOP3)</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>

Usually, these commands should be disabled for security purposes, but some other software may be able to use these commands for various reasons. In this case, you can enable them, but restrict access to the IP address(es) you trust.</description>

        <description>Spam Filter Rules

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.

This reference contains a definition of the spam filtering script language supported by VPOP3. Note that as later versions of VPOP3 are released, more language features may be added, so this reference indicates in which version of VPOP3 a particular feature was added.</description>

This lets you set whitelists &amp; blacklists for the spam filter.

There are four lists you can manage. The Whitelist Addresses &amp; Blacklist Addresses lists let you specify sender email addresses to check.

The main difference between IMAP4 and POP3 is that with POP3 the messages are only stored temporarily on the mail server until they are downloaded to the email client where the messages are stored, manipulated, searched etc. With IMAP4 the messages are stored permanently on the server, and they are manipulated, searched etc on the ma…</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>

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>

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>

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>

Disk Caching

One key point is that, like all other high-end databases, PostgreSQL should not be run on a server with disk level write back caching. With write back caching, the disk will report data as being written to disk when it is still in the disk&#039;s cache memory. If the power then fails, this data is lost and can cause database corruption. As long as the database server really knows when the data has been written to disk, power failure will not cause database corru…</description>

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>

Some ISPs (especially in Germany) require you to log on to collect your POP3 mail before they will allow you to send any mail through their SMTP relay servers.

VPOP3 actually connects to the POP3 server and SMTP server at the same time, so usually it will not have successfully logged onto the ISP&#039;s POP3 server before it tries to start sending mail.</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>Outbound Messages Not Appearing in Monitor Target Mailbox

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>

        <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>

By default VPOP3 makes a daily backup of the VPOP3 database to a file &#039;DBBACK-n.DMP&#039; in the VPOP3 installation directory (it is possible to change this in the settings). These are cycled on a weekly basis so you will usually have the last seven days&#039; worth of backups. These can be useful if the database gets damaged somehow.</description>

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 Responding Slowly

If VPOP3 is responding slowly to users there are several common causes:

	*  The VPOP3 server disk may be badly fragmented. Defragment the server disk(s). Note that sometimes the Windows defragmenter will say that the disk doesn&#039;t need defragmenting even if it does, so it is best to do it anyway. Also, there is a better free defragmenter available called</description>

Message Store

The Delay while moving messages setting tells VPOP3 how quickly to import messages into the new database structure if it was upgraded from version 2.x or earlier. Usually this is OK to be left as it is, but if there is some special requirement to import the messages more quickly, you can decrease this number, but that will increase the load on the server.</description>

This script lets you customise how VPOP3 sends DMARC reports to the sending domain.
