	*  Global Signatures
	*  Personal Signatures
	*  Webmail Signatures

Notes

When creating a signature it is generally best to keep it as short as possible. 

Disclaimers &amp; confidentiality notices in emails are generally regarded as having little or no legal significance, so lengthy signatures just use up bandwidth.</description>

The performance requirements for VPOP3 depends on many factors, so we can&#039;t give specific details for any scenario.

How to detect limiting factors

        <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>

Moving VPOP3 Version 3 or 4 to a new PC is slightly different from moving earlier versions, because of the database system.

The summary of steps is:

	*  Stop VPOP3 on the original PC
	*  Manually make a backup of the database on the original PC</description>

        <description>450 4.3.2 Content Filter Timeout

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>

By default VPOP3 v3 and later will automatically perform a daily backup of the database into a file called DBBACK-x.DMP, where the backup file rotates on a weekly basis (DBBACK-0.DMP is Sunday&#039;s backup, DBBACK-1.DMP is Monday&#039;s backup, etc).</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>

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.

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

        <description>How To: Move VPOP3

You can usually move VPOP3 without having to uninstall and reinstall. It is best to move VPOP3 rather than reinstalling from scratch on the new PC or in the new location, because that way you can keep all your existing settings, rather than having to try to recreate them.</description>

        <description>How to start VPOP3

There are two ways to start VPOP3

	*  as a service
	*  as a normal application

For normal operation, you will start VPOP3 as a service, as this means that VPOP3 will run even when no one is logged into the PC.
To help with some types of problem diagnosis it can be better to start it as an application. This makes VPOP3 run in the account of the currently logged in user, rather than the service account, so it can eliminate access permission problems. Also, when VPOP3 starts a…</description>

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>

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>

        <description>Inbox size is zero but mailbox size is not zero

In the VPOP3 settings sometimes, on the user account list the “Inbox Count” is shown as zero, but the “Mailbox Size” is not zero.

This is not a bug, or mistake - the two figures are showing different things.</description>

Simply download VPOP3 from the website, and run the installation program and follow the prompts.

Occasionally people may have problems with the PostgreSQL part of the installation. If that happens, please contact us either by email at support@pscs.co.uk or by phone to +44 (0)1484 855800, and we will do our best to help.</description>

A few ISPs use a non-standard and not recommended system of encrypting connections to their SMTP mail servers.

VPOP3 has a security feature which will lock out an account after it has had several failed login attempts. This feature is to make it harder for an attacker to use a brute force or dictionary password attack on an account.

The default settings are that after more than 3 attempts to log into an account with an incorrect password, VPOP3 will lock the account for 30 minutes. You can change these settings on the</description>

        <description>Mail Not Downloading From ISP

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>

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;).

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>

	*  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>
