Mail Relay Server

We have set up a mail relay server on lcls-prod03

• Make sure sendmail is set to startup and is running on lcls-prod03
  • service sendmail status
  • chkconfig --list sendmail
• Add the following line to /etc/mail/access
  • 172.27      RELAY
• Add the following to /etc/mail/relay-domains
  • slac.stanford.edu
• Restart sendmail services
  

On our Private servers:

• The "DS" line in /etc/mail/sendmail.cf need to be changed to "DSlcls-prod03.slac.stanford.edu"
  • This sets up the Smart Relay to lcls-prod03
  • sed -i s/^DS$/DSlcls-prod03.slac.stanford.edu/g /etc/mail/sendmail.cf
• Restart sendmail services

How to send mail from our PROD servers:

• Just send email the normal way as all mail will get relayed to lcls-prod03
  • brobeck@slac.stanford.edu
  • controls-system-admins@slac.stanford.edu
