Postfix Monitoring
Emailing is a classic means of internal or external business communication operated by a mail server. The server consists of several components turning it into a complex system. Each component enables a certain operation, like email receiving, delivery or resending. The components form an integrated system by tightly intercommunicating with each other. If a mailing system is used for communication with "external" recipients, its mail servers become available to the outside world which arises additional security risks and often leads to a higher system load.
One of the basic mail server components affecting its overall performance is a mail agent. Postfix is an open-source mail agent used by a plenty of mail systems all over the world. It builds a reliable and secure mail server base for small and medium-sized companies.

On top of that, such attacks may damage or completely block mail services. Keeping track of the server performance and status is obviously important to avoid downtime and potential dangers being also able to reduce the response time. Taking well-timed measures or being ready to shut the system down is a must-have strategy.
