I suggest that you take a few minutes to read it, and then proceed with the installation instructions. This is the first public release of the Postfix mail system. Thank you for your interest in this project. Send me a postcard if you like it. My postal address is below.
Postfix aims to be an alternative to the widely-used sendmail program.
A stunning number. Although IBM supported the Postfix development, it abstains from control over its evolution. The goal is to have Postfix installed on as many systems as possible. To this end, the software is given away with no strings attached to it, so that it can evolve with input from and under control by its users. In other words, IBM releases Postfix only once.
