SPF Sendmail milter uses libSPF2 library to implement Sender Policy Framework for Sendmail filtering easily.
This software review is for SPF Sendmail milter, which is a filter for Sendmail. The filter incorporates the Sender Policy Framework (SPF) technology with the help of the libSPF2 library. The purpose of the filter is to verify that emails have been authorized by the domain name they came from. This prevents email forgery, which is commonly used by spammers, scammers, and email viruses/worms.
The SPF Sendmail milter can reject messages on an SPF hardfail result and add the standard Received-SPF header with SPF results to the scanned messages. The filter's goal is to be lightweight, reliable, and simple, and it is written in C.
While the filter is stable, the libSPF2 library is beta software and may be unstable, which could affect filter stability. It is important to use the filter in a production environment with caution.
The SPF Sendmail milter has several key features, including a hosts/networks whitelist, the ability to reject messages on SPF hardfail result, the addition of a standard header with SPF results, and the logging of all filter activities to syslog. The filter's code is small, with no more than 320 lines, and it works quickly with low resource requirements. No temporary files are created during operation.
This release of the SPF Sendmail milter includes cosmetic enhancements. Overall, the filter offers a reliable and lightweight solution for verifying email authorization for Sendmail users.
