Configuring NetManager to be able to send email externally and to Exchange users

  1. Determine the email domain name ( in this example) and the IP address of the Exchange server ( in this example)
  2. Set mail relay on NetManager to the IP address of the Exchange server. 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. All non-local email will be sent to this server for onwards delivery.
  3. Set email domain on NetManager to the full email domain name. This can be done through Email > Send/Rcv in webadmin, from option I and then O on the Console Menu or by setting domain_external in the NetManager configuration file. This will cause email to be sent from, i.e. system mail will come from This step is sufficient for the NetManager to send email to external addresses (e.g. Precedence support)
  4. To deliver mail to users at the school, an extra step is required. As the local domain is set to be the main mail domain, the NetManager will assume that any email to should be delivered locally to user username (see here for more information). Therefore, no mail will be sent on to Exchange. To forward all mail for the domain to another server, you need to set mail_forward in the NetManager configuration file to the IP address of the mail server, i.e.
  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
  7. Test sending mail externally from the command line:
    netmanager 1# echo "Hello" | mail -s Test
  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:
