        <description>Database Maintenance

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>

        <description>Total Rebuild of Database

If you suspect database corruption, sometimes the best thing to do is to totally rebuild the database. This involves six steps:

	*  Stop VPOP3
	*  Backup Database
	*  Delete Database
	*  Re-create Database
	*  Restore/Create Database</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>How to estimate Database Upgrade Time

When upgrading from VPOP3 version 3 or 4 to version 5, the PostgreSQL database engine needs to be upgraded. This involves backing up the database data, upgrading the database engine, then restoring the data. This can take some time on large databases.</description>

        <description>How to filter attachments

VPOP3 can filter attachments in several ways.

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

VPOP3 can also filter attachments using the content/spam filter, or by using an integrated virus scanner.</description>

An incoming SMTP feed is where incoming mail is sent directly to your mail server without going through your ISP&#039;s POP3 mail server on the way. 

Advantages

An incoming SMTP feed has several advantages over going via a POP3 mailbox:</description>

        <description>How To Upgrade VPOP3 to version 5 or later

Upgrading VPOP3 is usually a straightforward process. Download VPOP3 from our web site and 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>

        <description>Message Archive -&gt; Offline Tab

Settings -&gt; Message Archive -&gt; Offline Tab.

The Offline tab lets you tell VPOP3 to move old archived messages to an alternative store, such as CD/DVD or external drive etc. VPOP3 will create a ZIP file containing the old messages. The archive index will still remember the messages, and the name of the ZIP file they are contained in, so you will still be able to search for messages on date, sender, subject, etc, but not on the message content.</description>

Every time VPOP3 is going to send messages using direct MX sending, it runs a script called mxout.lua which can be created/edited in Settings -&gt; Scripts (or in the VPOP3 directory in VPOP3 v6.6 or earlier).

Starting with v8.8, the following global variables are defined:</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>

This problem is primarily related to VPOP3 versions 2.5 -&gt; 2.6. Theoretically it could happen on later versions, but would be extremely unusual (see the note at the bottom if you are using version 3.0 or later)

        <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>
