Mail Service
Overview
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/mail.cf
.
postfix
is configured to accept mail from hosts on the admin and reject all others.
Redirecting Mail to Root
- Messages sent to root@usno.nrao.edu are redirected to usno-admins@nrao.edu. This is accomplised by two configuraiton mods.
- Two lines were added to
/etc/postfix/main.cf
-
virtual_alias_domains = usno.nrao.edu
-
virtual_alias_maps = hash:/etc/postfix/virtual
-
- The line
root@usno.nrao.edu usno-admins@nrao.edu
was put into the file /etc/postfix/virtual
to specify the actual email address redirection. This file already existed, although it was unused.
usno-admins mail alias
- Admins should be added to the usno-admins alias in the /etc/mail/aliases file on mail.aoc.nrao.edu. A helpdesk ticket is required.
- Current alias:
dropbox$ grep usno /etc/mail/aliases
usno-admins: mwainrig, aescobar, asmoake
