We have officially released the new SpamFilter ISP v3.1.3.597. It is available for download in the registered user area of our website.

In addition to a number of fixes and enhancements to the spam-image filter, this new version allows SpamFilter to authenticate users via Active Directory, LDAP and Unix-style password files. Authenticated users are whitelisted, allowing them to use SpamFilter as the "Outgoing SMTP Server" in their email client configuration. SSL over SMTP is available to allow for username/password encryption.

As always, this upgrade is free for all users with a current software maintenance.
