Mail Service


Since the correlator is effectively a compute device, very little email service is required. The only exception is that the system administration notifications need to be sent off cluster so that NRAO system administrators can be duly informed.

Server-1 provides mail service using postfix which is the RHEL preferred (mildly) daemon. The configuration files for postfix are located in /etc/postfix. The main one of interest is /etc/postfix/

postfix is configured to accept mail from hosts on the admin and reject all others.

      • virtual_alias_maps = hash:/etc/postfix/virtual

    • The line was put into the file /etc/postfix/virtual to specify the actual email address redirection. This file already existed, although it was unused.

  • Admins should be added to the usno-admins alias in the /etc/mail/aliases file on A helpdesk ticket is required.
  • Current alias:
