Tag: send as address

If you have scripts or other services that run as root that need to send to outside email addresses, via postfix, without being root@hostname, this is what you need to do:

1. 1.  sudo vi /etc/postfix/generic
      

      root name@tld.com

   2. sudo vi /etc/postfix/main.cf
      

      smtp_generic_maps = hash:/etc/postfix/generic

   3. sudo postmap /etc/postfix/generic
   4. sudo systemctl restart postfix

Done! Now root will send as name@tld.com instead. Substitute whatever you want for name@tld.com
