3.8. Configuring Satellite Server for Outgoing Emails

Procedure

1. In the Satellite web UI, navigate to Administer Settings.

2. Click the Email tab and set the configuration options to match your preferred delivery method. The changes have an immediate effect.

   1. The following example shows the configuration options for using an SMTP server:

      Expand

      表3.1 Using an SMTP server as a delivery method

      Name	Example value
      Delivery method	SMTP
      SMTP address	smtp.example.com
      SMTP authentication	login
      SMTP HELO/EHLO domain	example.com
      SMTP password	password
      SMTP port	25
      SMTP username	user@example.com

      Show more

      The SMTP username and SMTP password specify the login credentials for the SMTP server.

   2. The following example uses gmail.com as an SMTP server:

      Expand

      表3.2 Using gmail.com as an SMTP server

      Name	Example value
      Delivery method	SMTP
      SMTP address	smtp.gmail.com
      SMTP authentication	plain
      SMTP HELO/EHLO domain	smtp.gmail.com
      SMTP enable StartTLS auto	Yes
      SMTP password	password
      SMTP port	587
      SMTP username	user@gmail.com

      Show more

   3. The following example uses the sendmail command as a delivery method:

      Expand

      表3.3 Using sendmail as a delivery method

      Name	Example value
      Delivery method	Sendmail
      Sendmail arguments	-i -t -G

      Show more

      The Sendmail arguments specify the options passed to the sendmail command. The default value is -i -t. For more information see the sendmail 1 man page.

3. If you decide to send email using an SMTP server which uses TLS authentication, also perform one of the following steps:

   • Mark the CA certificate of the SMTP server as trusted. To do so, execute the following commands on Satellite Server:

     # cp mailca.crt /etc/pki/ca-trust/source/anchors/
     # update-ca-trust enable
     # update-ca-trust

     Copy to Clipboard Toggle word wrap

     Where mailca.crt is the CA certificate of the SMTP server.

   • Alternatively, in the web UI, set the SMTP enable StartTLS auto option to No.
4. Click Test email to send a test message to the user’s email address to confirm the configuration is working. If a message fails to send, the web UI displays an error. See the log at /var/log/foreman/production.log for further details.
