SAOP software enhances SMTP server security with authentication, by utilizing POP3 or IMAP4 server as a back-end.
By sitting in the middle of an SMTP session and intercepting login attempts, saop is able to capture the user and password, using them to authenticate against either a POP3 or IMAP4 server or a password list. This makes the process of authenticating your users easy and hassle-free.
Originally created for the IIS SMTP service on Windows, saop has since been adapted to work on Linux as well. In fact, some users have reported that it works even better on Linux than it does on Windows! Regardless of the platform you're running, saop is an excellent solution that allows your SMTP service to authenticate users with the same user/password as the POP3 service without defining local users.
Saop is highly flexible and works with a variety of servers, including Postfix and Dovecot. It should be able to run with any server combinations. Plus, it installs as a service on Windows and runs at startup, making it incredibly easy to use.
Finally, saop doesn't have any dependencies apart from a pthread library, and it's licensed under the GPL. This means that you can use it with confidence, knowing that it's both reliable and cost-effective. So why wait? Download saop today and start using it to secure your SMTP server!
