        <description>SMTP Server -&gt; IDS/IPS

The IDS/IPS tab lets you set logging and automatic blocking parameters for the IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) component of the SMTP server.

SMTP servers are regularly attacked, both by incoming mail attacks (spam/viruses etc) and relay attacks (by spammers and other malware distributors trying to send mail through them). Because of this, there is a system in VPOP3 which will track attack attempts on the SMTP service and can automat…</description>

        <description>Spamfilter White/Blacklists

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. With the default rule weights, if a sender&#039;s address is on the Whitelist, it will be allowed through the spam filter, and if it is on the Blacklist it will be blocked. If an address is on both the Whitelist and the Blacklist, they will cancel each other out, and the me…</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>

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>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>

        <description>How To Allow Mail Relay Through VPOP3

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>

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>

To set up an iPhone to access VPOP3&#039;s mail, you first of all need to configure VPOP3 to allow access by remote users (unless you will only be using the iPhone in the office, connected via WiFi to the office LAN).

        <description>Require SMTP Authentication

There are some situations where VPOP3 needs to know who is sending mail. This may be if you have VPOP3 configured to behave differently depending on who is sending messages - eg if you have different message size limits depending on the sender, or if you have message monitoring configured for certain users, or you don&#039;t want certain people to be able to send mail at all.</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>

        <description>Autoresponder

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.

They can be used to copy messages, mark them as read, delete them, etc

VPOP3 will process Message Rules in the order they appear in the list. If you want to change the order of the rules, you can drag &amp; drop them into the correct order. Usually when VPOP3 has processed a rule, it will go on to check further rules, but you can use the</description>
