SpamMover: Exchange Server folder integration with third-party antispam products

Many third-party antispam software products for Microsoft Exchange Server pre-classify email by adding an X-header or subject line modification that either marks it as spam or legitimate email. Learn about a Microsoft Exchange Server add-on called SpamMover that can automatically sort that pre-classified email into administrator-specified Microsoft Exchange Server mail folders.

Many third-party antispam software products for Microsoft Exchange Server (or for generic SMTP/POP3 email systems) pre-classify email by adding an X-header or subject line modification that either marks it as spam or legitimate email.

While it's possible to configure Microsoft Exchange Server to automatically handle email messages that are pre-classified by a third-party antispam product, sometimes it's beneficial to have a tool do the heavy lifting for you ahead of time.

That's the idea behind SpamMover, an add-on for Microsoft Exchange Server that automates most of the process of handling pre-classified email.

SpamMover creates a custom folder within each Microsoft Exchange Server mailbox to receive spam. It scans incoming email for up to four given headers, which can be freely defined and customized by the administrator. Email with those headers is then moved to the designated target folder.

The values of the headers can be a specific value ("YES,""NO") or can be within a range of values, as per the Spam Confidence Level (SCL) rating that Exchange Server assigns to incoming messages.

The SpamMover event sink can be registered across all mailboxes in a Microsoft Exchange Server installation (the default setup), or only on specific mailboxes. It can also be registered globally and then selectively de-registered -- i.e., you can install it in all but a select set of mailboxes.

Additionally, the SpamMover installer lets you configure the event sink priority. This means you can set it to run after other items if you have more than one email-processing event sink at work.

SpamMover can be configured to run in an active/passive Microsoft Exchange Server cluster as well. To do this, it needs to be installed on both nodes of the cluster (there are specific directions for doing this in SpamMover's documentation).

Finally, there's a demo version available that runs on a single, specially designated Microsoft Exchange Server mailbox. The full version is U.S. $100 for a single Exchange server. There are discounts for multiple servers, and whole-site licenses complete with the source code.
