Simphony MFA Configuration Prerequisite Requirement

For MFA implementation, you must install and make network accessible, two separate Simple Mail Transfer Protocol (SMTP) email servers (each to be designated as either a Primary or Backup server). This allows you to receive a one-time-password (OTP) via email, each time you attempt to log onto the EMC. An SMTP Backup server is required to provide EMC access redundancy in the event that the Primary SMTP server fails for any reason.
