By default, SmarterMail installs a basic web server that allows administrators to start using the application immediately after installation. However, SmarterTools recommends moving to a more robust and secure Web server, such as Microsoft IIS.

NOTE: This topic assumes that you have IIS installed and are familiar with how it works. if you are unfamiliar with or uncomfortable using Microsoft IIS you can use the Web server included with SmarterMail. It is also recommended to be up to date with all software patches.

Applies to SmarterMail 8.x - 15.x
