VPOP3 Requirements

The minimum requirements for VPOP3 are below. Note that the requirements will increase depending on what else the VPOP3 computer is used for, how many user's you have defined in VPOP3 and how much mail they receive and send.

The VPOP3 computer does not need to be dedicated to running VPOP3, so you should take into account the requirements for the other software.

Recommended Requirements for VPOP3 Server

• Windows 2000 or XP or later
• Computer with 1GHz Pentium 4 (or higher) processor. (Note that it may run on a slower PC, but the performance may not be acceptable). VPOP3 will utilise multiple processors or multicore processors fully.
• 512MB RAM. (If you turn off the spam filtering facility, then the memory usage will be considerably less)
• 40MB Hard disk space required for VPOP3 itself. Extra space will be needed for email storage
• Internet Explorer 5.5 or later for WebMail and WebAdmin ⁽¹⁾
• Internet connection (eg Modem, ISDN Terminal adapter, xDSL connection or Router connection)
• Internet account with email facilities (in most cases) ⁽²⁾
• TCP/IP networking on the local network

Minimum Requirements for VPOP3 Server

• Windows 95 or Windows 2000 or later. (VPOP3 2.4.0 and earlier should work on NT4. Later versions MIGHT work on NT4 but it depends on which DLLs have been installed in the past, eg certain files were distributed with IE4, but not with later versions of IE)
• Computer with Pentium (or higher) processor. (Note that it may run on a slower PC, but the performance may not be acceptable)
• 64MB RAM (for a 25 user installation). Note that certain operating systems require more memory. For instance, for Windows XP and later a minimum of 256MB is normally recommended.
• 40MB Hard disk space required for VPOP3 itself. Extra space will be needed for email storage
• Internet Explorer 5.5 or later for WebMail and WebAdmin ⁽¹⁾
• Internet connection (eg Modem, ISDN Terminal adapter, xDSL connection or Router connection)
• Internet account with email facilities (in most cases) ⁽²⁾
• TCP/IP networking on the local network

(If you only have the minimum requirements, it is recommended that features like Spam Filtering, virus scanning etc, are turned off)

Workstation computers can run any operating system which supports TCP/IP, and need suitable Internet email client software (any email software which supports POP3 & SMTP is suitable)

VPOP3 Enterprise will typically require a faster processor and more hard disk space than VPOP3 Standard, because IMAP4 mail storage places a higher load on the server than POP3 does.

Notes:

1. WebMail and WebAdmin also work with most other 'latest' web browsers - eg Opera 9, Mozilla Firefox etc.
2. If you have a permanent Internet connection you can use VPOP3 with a direct incoming SMTP feed (by setting up MX DNS records to point to the IP address of the VPOP3 computer). You can also tell VPOP3 to use direct sending of outgoing mail so you don't need to use an ISP's SMTP relay server either.
