VPOP3 Email Server

Why upgrade?

Why upgrade to version 6.0 from version 5

The main changes between version 6.0 and version 5 are:

Configurable bandwidth limits for VPOP3 services
POP3 service can 'hold' messages rather than delete them, as a crude backup facility
Have options to hold messages for a certain time once they arrive in the outqueue, and to delete them if they have been in the outqueue for a long time. Eg, you could say to hold messages for 10 minutes after they are sent, so that there is chance for a message to be deleted before being sent, or you could say that messages should be held for 10 days, so that they have to be manually released before they can be sent. This can be set globally or for individual users, or even scripted using Lua
Support mass deletions/holds for outqueue messages, using searches to be able to filter messages to hold/delete
Add security lockouts to IMAP4/Webmail/POP3 for IP addresses which repeatedly attempt to login using bad details
Lots of improvements to CalDAV support for better compatibility with iPads, Macs, Android phones and other devices/software
Improvements to Webmail
Make it easier to store the Archive main store on a network share
Can Pause/Unpause scheduling from the status monitor
Some improvements to Download Rules
And lots more

Why upgrade to version 5 from version 4

The main changes between version 5 and version 4 are:

Webmain includes Calendar support
Message Rules (VPOP3 Enterprise) to filter incoming messages to different folders on the server
Autoresponder improvements to allow easier configuration of multiple autoresponders, or multiple triggers for autoresponders
Uses PostgreSQL 9.1 to allow replication of database for warm standby servers
All message data is stored in the database to allow easier restores/migrates, and replication to standby servers
Most configuration data is now in the database to allow replication of configuration changes to standby servers as well
Partial restore from backups (VPOP3 Enterprise)
Message 'recycle bin' to undo accidental deletes easily (VPOP3 Enterprise)
Simple mobile compatible Webmail
SPF support (with VPOP3 Enterprise or active Spamfilter subscription)
BATV support
IPS/IDS support
Improved performance when clearing large inboxes or deleting users
Configurable quarantine report times
Configurable database backup times
Ability to turn off 'database backed up successfully' messages
Sending quotas for users
Improved MX sending support
Ability to selectively re-download messages from remote POP3 servers
Fix errors with non-ASCII characters in several places
Pay-as-you-go SMS support
Pay-as-you-go Fax support
And lots more

Note that as from version 5.0, Windows 2000 is no longer supported. You need Windows XP/2003 or later to run VPOP3.

Version 5 is a major upgrade from version 4, so you will need a new licence key, which will be free if you have an active Upgrade Protection plan. To obtain or buy the upgrade, go to the VPOP3 Upgrade page.

Why upgrade to version 4 from version 3

The main changes between version 4 and version 3 are:

VPOP3 has a totally rewritten WebMail system. This is more friendly, allowing things like drag/drop of messages into folders, address completion when sending messages etc.
There is an experimental CalDAV server. CalDAV is an open system for sharing calendar information with a suitable client. This has been tested with Mozilla Lightning (a plugin for Thunderbird) and Mozilla Sunbird (a standalone calendar program). VPOP3 Standard allows a single calendar per user, accessible by that user. VPOP3 Enterprise allows multiple calendars per user, along with customisable sharing between users. (The Home User licence does not include the CalDAV facility).
The Address Book system has been re-worked. Now, users can define their own address books, and some of the quirks of the previous address book in that situation have been fixed. In VPOP3 Enterprise, users can create multiple LDAP/WebMail address book, and share them between users.
Support has been added for Pay-As-You-Go Fax and SMS support which don't require a modem, but where the faxes & SMS messages are sent via the Internet.
Lots of smaller changes and bug fixes

Why upgrade to version 3 from version 2

The main changes between version 3 and version 2 are:

VPOP3 now has a totally rewritten message store system. This is much quicker, especially for users with large numbers of messages in their mailboxes - especially VPOP3 Enterprise users, and heavy users of Webmail. The new message store is also more reliable.
VPOP3 has a totally rewritten administration interface, which is much easier to use and more intuitive. The vast majority of people who have upgraded prefer it.
There are lots of other smaller changes as well, such as faster LAN forwarding queueing system, multiple active archive searches etc.

The above changes may not seem much, but they involved large changes to the underlying structure of VPOP3 to enable more changes in the future.

Note that as from version 3.0, Windows 95, 98, ME and NT4 are no longer supported. You need Windows 2000 or later to run VPOP3.
