URI-milter is a simple and lightweight milter with one single purpose: Check the mail body for Spam URIs using several SURBLs.

Even though there are several programs for this job, most of them are generic anti-spam tools which perform SURBL checking among other tasks. URI-milter was written out of the need for a simple and fast program performing only this task.

It is written in the C language utilizing the sendmail milter API, so it checks the mail during the SMTP transaction allowing many possibilities like rejecting the mail.

URI-milter is being developed and used succesfully in the University of Athens and is being released to the public under the latest GPL license.
