Postfix for budget conscious senders
Postfix is an Open-Source email message transfer agent (MTA) created by Wietse Venama as an alternative to Sendmail.
One of the biggest MTAs in the World with 200K instances. Postfix drives email for website editors, ESPs and other major senders.
Well used and optimized, this open source MTA could be an alternative to commercial MTAs for small companies and low budgets. In order to reach this high level of usage, Postfix needs to be integrated with a real-time log analysis to implement the best practices and update the settings each time it is necessary.
