At A Glance: Postfix

Whether it’s wishing Mom a happy birthday with a celebratory e-card or sending an urgent message to the boss, email is an important part of everyday life and an essential form of communication. An undeliverable email is a breakdown in communication, and when a critical message doesn’t reach its destination, it can send the day into a tailspin. Similarly, an inbox cluttered with potentially virus-laden spam mail causes congestion and makes a computer more vulnerable to malware or other viruses that may be contained within innocuous-looking junk messages. Postfix is a free, open-source mail transfer agent that can help protect users from potentially harmful spam mail by accepting emails only from trusted sources. Postfix runs on a variety of systems, including AIX, BSD, HP-UX, IRIX, Linux, MacOS X, Solaris, Tru64 UNIX, and other UNIX systems. Postfix is particularly useful for businesses, as it allows office users to securely communicate amongst themselves without fear of widespread damage to the network.

A Postfix SMTP server professional can assist you or your business in implementing this valuable, free tool. On Upwork, you’ll be able to browse through a global network of experts who can offer their support in a variety of ways. If you’re having trouble with an existing Postfix system, these professionals can troubleshoot the problem to quickly get you back on track. If you’re looking to install Postfix, any one of the multitude of freelancers you’ll find on Upwork’s global marketplace can help you do so. Or if you simply require help managing Postfix or navigating its features, these specialists are there to help too.
