Configuring User E-mail Address

By default, Proxmox will try to use the domain portion of the "Email from address" as the e-mail relay server.
 
   01. Select Datacenter ≫ Options from the left navigation menus
   02. Double click the Email from address field
   03. Enter the e-mail address that Proxmox will send outgoing e-mails from ≫ Click OK
   04. Expand Datacenter ≫ Select the node name ≫ Click Shell in the left navigation menus
   05. Run the following commands in the terminal
         send a basic test email
         echo "Test email from Proxmox: $(hostname)" | /usr/bin/proxmox-mail-forward
         output the mail log
         cat /var/log/mail.log
   06. Notice the relay is the domain (i12bretro.local) from the Email from address setting

   03. Comment out mydestination by adding a # to the beginning of the line
   04. Press CTRL+W and search for relayhost
   05. Comment out relayhost by adding a # to the beginning of the line
   06. Update or add the following configuration
         relayhost = smtp.gmail.com:587
         smtp_use_tls = yes
         smtp_sasl_auth_enable = yes
         smtp_sasl_security_options =
         smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
         smtp_tls_CAfile = /etc/ssl/certs/Entrust_Root_Certification_Authority.pem
   07. Press CTRL+O, Enter, CTRL+X to write the changes
   08. Continue with the following commands in the terminal
         create /etc/postfix/sasl_passwd

   11. Continue with the following commands in the terminal
         update postfix lookup tables

         chmod 600 /etc/postfix/sasl_passwd
         restart postfix service
