Spam Filter

Unlike other email archiving solutions, MailShelf allows you to filter spam and junk emails in order to completely exclude them from archiving so you can always keep your archive clean from such emails.

In order to detect spam and junk emails, MailShelf fully supports the SpamAssassin protocol which enables you to fully integrate SpamAssassin directly into MailShelf so that any email that should be archived can be checked for spam characteristics before archiving it.

Thanks to the SpamAssassin support, you can take advantage from a variety of spam-detection techniques, including DNS-based and fuzzy-checksum-based spam detection, Bayesian filtering, external programs, blacklists and online databases.

In addition and to get even better spam and junk filtering results, MailShelf comes with a complete integration for DNSBL queries, which allows you to lookup the sender IP address of each email to be archived in online databases to determine whether the corresponding email is spam or not.

If you currently have a high spam or junk email appearance, MailShelf can help you to exclude them from your archive.
