Sending system reports if NetManager is not your main mailserver

Configuring NetManager to be able to send email externally

 and to users on an alternative local mail server (e.g. Exchange)
  1. Determine the email domain name (school.lea.sch.uk in this example)
  2. Determine what mail relay to use, if any. This could be any of:
    • On-premises mail server (e.g. Exchange)
    • ISP SMTP relay
    • Authenticated sending via Gmail (see here for details)
    • Send direct, no relay
  3. Set mail relay on NetManager to the IP address of the mail relay (or leave empty to send direct). This can be done through Email > Send/Rcv in webadmin, from option I and then M on the Console Menu or by setting mail_relay in the NetManager configuration file. If configured, all non-local email will be sent to this server for onwards delivery.
  4. Set mail_local_domain in the NetManager configuration file. This will cause email to be sent from user@school.lea.sch.uk. Do not configure a local domain (using the console menu, webadmin or domain_external configuration setting) as this will make the NetManager believe that mail for school.lea.sch.uk should be delivered to itself
  5. Once the changes have been made, you must run build_server to make the changes live. Do not be tempted to run just the sendmail build script.
  6. To receive system mails, set an email alias from root to a suitable user account @school.lea.sch.uk
  7. Test sending mail externally from the command line:
    netmanager 1# echo "Hello" | mail -s Test my.account@googlemail.com
    
  8. Test sending mail to root internally from the command line:
    netmanager 1# echo "Hello" | mail -s Test root
    
In summary, the NetManager configuration file should contain:
mail_relay="10.0.0.100"
mail_local_external="school.lea.sch.uk"

  7. On the Remote Network settings page, select the default 0.0.0.0-255.255.255.255 range and click the X button above to delete
  8. For each NetManager, click on Add... and enter its IP address. When you have added all, click Next >
  9. Review settings and click New
  10. Once completed, click Finish
