KB06020601 Managing Windows IISMailtraq is fully compatible with Windows Server editions - but you may need to resolve some 'conflicts' with the default services Windows provides.
There are two likely conflicts:
Windows provides IIS - Internet Information Service - which is normally installed by default - to host websites and provide a basic message service using the Simple Mail Transfer Protocol (SMTP).
Mailtraq will now be providing the SMTP services for the server - so you need to 'turn off' Windows SMTP service in IIS.
If you are not running a website from the machine then you should completely 'turn off' IIS. If you are running a website from the machine, just stop the Windows SMTP service - and read the note at the bottom of this page.
Web Server in Mailtraq
Note that Mailtraq also provides a full web server as part of your Mailtraq Professional License, so if 'all' you wish to use IIS for is to serve a regular website, you can use the built-in webserver - read more here.
1. Stop just the Windows SMTP service
Go to Windows Start | Control Panel | Services
and select Simple Mail Transfer Protocol (SMTP)
Then click the 'Stop' link in the left column.
This will stop only the Windows email service so that Mailtraq can replace it.
In order to make this action permanent, open the Service and set 'restart' to manual, otherwise when you reboot IIS-SMTP will restart.
2. Stop Windows IIS Admin Service
Go to Windows Start | Control Panel | Services
and select IIS Admin Service
Then click the 'Stop' link in the left column.
This will stop both Windows mail and web services so that Mailtraq can replace them.
In order to make this action permanent, open the Service and set 'restart' to manual, otherwise when you reboot IIS will restart.
Configuration Tips:
One service - one port
Running a web-site and webmail on the same server. HTTP services (i.e. a website and webmail) run by default on Port 80 - but you may offer only one service per Port. So, in order to resolve this conflict you will need to change the port that Mailtraq offers webmail on. This is explained here. |
