Let's examine the fields for outgoing email configuration:

  • Name: Allows you to designate a name for the outgoing mail server.
  • From Filtering: Specify the email address or domain for which this server can be utilized.
  • Priority: When no specific mail server is requested, the one with the highest priority (default is 10) is used.
