SmarterMail System Requirements

SmarterMail was designed to operate efficiently with multiple applications on the same server. Below are the minimum system requirements solely for SmarterMail. If SmarterMail is running on a server with other applications, those need to be taken into consideration and may add to the requirements listed below. In addition, high-load / high-volume servers may need to adjust the requirements as needed:

  • Windows Server 2012 R2 64-bit or higher - SmarterMail uses web sockets, which are not supported in IIS 7.5 or earlier.
  • Microsoft .NET 4.7 Framework
  • 4GB RAM
  • 2-core CPU
  • 100MB disk space for installation, not including mail data, file storage, etc.
  • Dedicated IP address
  • Active internet connection
  • Microsoft Internet Information Server (IIS) Note: SmarterMail no longer includes a default web server.
  • Dedicated App Pool
  • Minimal IIS Settings
    • Application Development Features
      • .NET Extensibility
      • ASP.NET

Can SmarterMail Be Installed on Amazon's EC2 Platform?

To put it simply, yes. However, Amazon's EC2 platform, and other cloud providers, have some things to consider when determining how well any mail server will run. For example, some cloud services rotate the IP addresses that are used, which can cause issues with items like DNS records and affect mail delivery. Some have issues with disk I/O or have various other issues that adversely affect SmarterMail's performance. Therefore, while you can install SmarterMail on a cloud service such as Amazon's EC2, it is not necessarily recommended.

Note: Each installation and environment is unique. Extra load caused by excessive messages or email accounts and/or other factors may require more disk space, memory, CPUs and/or CPU cores, database allocation, etc. than suggested in the Online Help. SmarterTools recommends that system administrators slowly add domains to the server and watch how they impact the server. In addition, email patterns indicate that the number of email messages per account are increasing by approximately 60% every two years. It is important to keep this growth in mind when planning your rollout.
