SmarterMail Server Requirements

The requirements of SmarterMail are minimal, so that SmarterMail can coexist with other applications on the same server. Below you will find the minimal requirements and a sample installation which may help you decide how much your hardware can process.

Minimum Requirements

  • Windows 2000, Windows XP, or Windows 2003 (all versions)
  • RAM: 128mb
  • CPU: PIII 500
  • DISK: 150 Megs
  • IIS 5 or higher (Required if you will not use the SmarterMail Web Server)

It is suggested customers use IIS in place of the SmarterMail Web Server to provide additional security and stability. The intended purpose of the SmarterMail Web Server is so that the product is fully functional even without the existence of a marketed web server. IIS is an enterprise level web server, however, and SmarterMail takes advantage of many features in IIS which will provide the highest return on investment.

NOTE: All installations are different, and extra load caused by excessive messages or email accounts may skew the server requirements. SmarterTools recommends adding domains slowly to the server once you get close to these limits and watching how they impact your server. Also, it is important to realize that email patterns indicate that email messages per account are increasing roughly 60% every two years. Keep this growth in mind when planning your rollout.
