What is Postfix?

Postfix, a mail server created by Wietse Venema at IBM research, serves as a practical alternative to the widely-used Sendmail program and is continuously updated and improved by Wietse in his role at Google. This powerful mail server is compatible with a range of UNIX systems, such as AIX, BSD, HP-UX, IRIX, LINUX, MacOS X, Solaris, and Tru64 UNIX, and operates with the requirements of ANSI C, a POSIX.1 library, and BSD sockets. Focused on speed, user-friendly administration, and robust security, Postfix presents a user interface similar to that of Sendmail, but its underlying framework is fundamentally different. It boasts several advanced features, including support for multiple SMTP deliveries over a single TLS-encrypted connection by utilizing tlsproxy(8) and scache(8) services and the capability to execute MySQL stored procedures. Furthermore, Postfix includes a gradual degradation feature that enables the daemon to log warnings and persist in functioning even when minor service issues arise, avoiding abrupt terminations due to fatal errors. Additionally, it can activate the execute bit on a queue file, a crucial aspect since failing to do so could hinder successful mail delivery. Collectively, these features establish Postfix as an adaptable and reliable option for effective mail server management, making it a favored choice among administrators seeking a robust solution for their email needs.

What is ClrStream?

Approximately one-third of businesses that experience a data breach see a reduction in revenue, with email consistently being the most targeted avenue for attacks. Safeguard your email systems with ClrStream, a thorough security and continuity solution compatible with platforms like MS Exchange, Office 365, MDaemon, Postfix, Postmaster, and Zimbra. Alarmingly, 88% of organizations experience data loss, with email often being the leading cause of these incidents. ClrStream operates as an email scrubbing service that protects against Malware, Ransomware, Viruses, and Spam, while also ensuring low latency for email delivery and reducing the rate of false positives. This solution serves as an external safeguard against DDoS attacks, providing an additional layer of security. Additionally, it offers email continuity when the main mail server is down or unreachable, incorporating built-in redundancies and scalability that eliminate the need for a mail parking service. As a cloud-based SaaS solution, ClrStream not only helps reduce bandwidth congestion but also streamlines management duties for organizations. By implementing this powerful solution, companies can significantly bolster their email security and enhance their ability to operate smoothly under adverse conditions. In today's digital landscape, investing in such protective measures has never been more crucial for maintaining trust and reliability with clients.
