POP connectors / pullers for Exchange

One of the challenges I often get asked about is “how can I use the Intellegent Message Filter on SBS 2003 if I am using the POP connector?”

The answer is that there are many POP connectors / pullers that essentially pull down the email from a POP account and then simply pass the mail to the Exchange server via SMTP. Here is a brief list which includes ones I have used in the past and others I have not. This list has been primarily taken from an article found on slipstick – a great resource!.. To see the full article click here. If you have any other suggestions, please let us all know!

ARX POP3 Connector

Supports filtering rules and DNS verification on incoming messages to reduce spam.

EFS (Email Forwarding Server)

EFS is a FREE POP3 gateway for any SMTP server such as Microsoft Exchange. It pulls mail from a Pop3 mailbox at your ISP and distributes the messages to users on a local SMTP mail server. EFS requires you to have a registered Internet domain name (to accept and forward mail for).

EMP (Extensible Messaging Platform)

Antispam security software that includes a POP3 connector. Works with Exchange 2000, as well as earlier versions.

Exchange Connector

Exchange Connector allows you to integrate your existing POP3 mailboxes with Microsoft Exchange Server 2000 or 2003 by downloading mail from POP3 mailboxes and delivering the messages to your Exchange Server accounts. Exchange connector runs in the background as a Windows Service and can be configured to download only during specified hours, such as between 9AM-5PM Monday-Friday and includes a “Download Mail Now” button for immediate downloads. It provides support for APOP (enhanced POP3 security), archiving, and SQL Server logging.

An included spam filter allows to tag or to delete mails that have been identified as spam by SpamAssassin.
