Do you need a Mailserver for Testing Purposes? Communigate Pro!

When I am testing Oracle and other software, I want to verify functions like sending alert mails. On Linux systems it’s easy. The most distributions have packages like sendmail already preconfigured and ready to use. But for example on Windows systems, there is no built-in solution. The goal was to have a small virtual machine running as mailserver which can be used for all my test cases.

CommuniGate Pro

CommuniGate Pro is a groupware which supports a lot of solutions like SMTP, POP3, Webmail and many more. In this post I describe how you can easy install the software and configure the SMTP component in Oracle Enterprise Linux 6.

The goal is to use CommuniGate Pro for the Enterprise Manager 13c to send mail alerts. Note: If you want to use CommunigatePro in your company, then you have to license it.

Software Download

The Software is available for the most platforms here:
Link to the installations guides:


I use the rpm file which I have already transferred to my server into directory /tmp. The installation has to be done as user root.

[root@olten tmp]# rpm -i CGatePro-Linux.x86_64.rpm
installing Startup Script
Removing the old mail link
creating a link for the new mail application
creating startup script links

The software is now installed in directory /opt

[root@olten tmp]# ls -la /opt
total 16
drwxr-xr-x.  4 root root 4096 Feb  3 08:35 .
dr-xr-xr-x. 25 root root 4096 Feb  3 08:30 ..
drwxr-xr-x.  8 root mail 4096 Feb  3 08:35 CommuniGate
drwxr-xr-x.  2 root root 4096 Mar 26  2015 rh

The installation routine creates the runlevel startup script that the software will be started automatically during server boot.

[root@olten tmp]# ls -la /etc/rc.d/init.d/CommuniGate
-r-xr-xr-x. 1 root root 2795 Feb  3 08:35 /etc/rc.d/init.d/CommuniGate

If you have already mail solutions like sendmail or postfix up and running, you have to stop and disable it.

Oracle Linux 6 – Stop postfix

[root@olten ~]# /sbin/chkconfig postfix off
[root@olten ~]# service postfix stop

Oracle Linux 6 –  Stop Sendmail

[root@olten ~]# /sbin/chkconfig sendmail off
[root@olten ~]# service sendmail stop

Start CommuniGate Pro

You can a) reboot your server or b) start it manually:

[root@olten tmp]# /etc/rc.d/init.d/CommuniGate start
CommuniGate Pro Base Directory /var/CommuniGate created
Starting CommuniGate Pro Server... Started.

Web Access Configuration – Step by Step

Initial Configuration:
Quick Start:

When the server is started, you can now access the web GUI by server URL and Port 8010.

Step 1 – Master Password

Set master password for user postmaster – I agree.


Step 2 – Server Name and Interface Mode

Verify server name and language, set interface mode to Advanced –  Update.


Step 3 – Create Account

Tab Users – insert new account name –  Create Account.


Step 4  – Set Real Name and Password

Set the Real Name and the CommuniGate Password for the new created user – Update.


Step 5 – Add Client IP

In tab Settings – Network – Client IPs add your client ip address or address range – Update.


Configure Client – for Example Oracle Enterprise Manager 13c

Set Host, User Name and PasswordOK.


Now you will receive the messages from EM13c.




With telnet you can verify if the correct SMTP service is running on port 25 and if the firewall is open.

Wrong Service

[root@solothurn ~]# telnet olten 25

220 ESMTP Postfix

Right Service

[root@olten ~]# telnet olten 25
Connected to olten.
Escape character is '^]'.
220 ESMTP CommuniGate Pro 6.1.8 is glad to see you!


Communigate Pro offers you an easy to configure SMTP platform. I have configured a small virtual machine which I start whenever I want to test some email functions.

Sure, this software can do much more. But all I want is to send emails from my test servers – Mission accomplished!
