The Software is available for the most platforms here: Note: If you want to use CommunigatePro in your company, then you have to license it. The goal is to use CommuniGate Pro for the Enterprise Manager 13c to send mail alerts. In this post I describe how you can easy install the software and configure the SMTP component in Oracle Enterprise Linux 6. CommuniGate ProĬommuniGate Pro is a groupware which supports a lot of solutions like SMTP, POP3, Webmail and many more. The goal was to have a small virtual machine running as mailserver which can be used for all my test cases. But for example on Windows systems, there is no built-in solution. The most distributions have packages like sendmail already preconfigured and ready to use. When I am testing Oracle and other software, I want to verify functions like sending alert mails.
