SmarterMail Error: 'IPC Port: Access is Denied'
This article describes how to resolve the 'IPC Port: Access is Denied' error message.
If you have recently installed the latest version of SmarterMail on your server, and are now receiving an error message which says, ‘IPC Port: Access is Denied’, this can be easily resolved by changing a certain line in SmarterMail’s ‘web.config’ file to point it back to the server.
First, open up ‘My Computer’ and navigate to ‘C: à Program Files à SmarterTools à SmarterMail à MRS’.

Inside the directory, there should be a file named, ‘web.config’. Right-click on the file and choose ‘Open With’, and then ‘Choose Program’. Depending on whether or not a configuration file has been manually opened your server previously, you may be able to double-click on the file and it will open automatically with Notepad.

Once the ‘Choose Program’ window is open, choose the ‘Notepad’ application to open the file. Make sure to uncheck ‘Always use this program to open this type of file.’
Once open, look for the line which says:
<add key="MailServiceAddress" value="IPC"/>

Now, edit the ‘IPC’ to read ‘127.0.0.1’. It should now look like this:

Please make sure to only change this setting, as making any other changes to web.config file can cause SmarterMail to cease to function correctly, and may require a reinstallation of the program.
Once done, restart the SmarterMail service, which you can do by navigating to ‘Start à Administrative Tools à Services’.

In the Services window, scroll down to the entry which says, ‘SmarterMail Service. Right-click and choose the option for ‘Restart’.

This will restart the SmarterMail service, and once completed, you will be able to log into the web interface without the error regarding the IPC port.
