Instructions

The Data Domain (DD) can be configured with an outgoing SMTP server for relaying email (for example, daily ASUPs).

By default, the DD connects to the configured relay on port TCP 25, but depending on the user setup, the port may be a different one.

Procedure:   
To change the outgoing SMTP port:    
  1. Log in to the DD as "sysadmin" or a similar user
  2. NOTE: SE commands have been deprecated in DDOS versions 7.7.5.25, 7.10.1.15, 7.13.0.15, 6.2.1.110 and above and are accessible only by Dell employees
  3. From SE mode, change the registry key which sets the outgoing SMTP client port to use.
For example:    
#### This command will return no output if a non-default port is set
# reg show config_master.net.smtp_port
#
#### To set a port other than the default, i.e: . 587
# reg set config_master.net.smtp_port 587
# reg show config_master.net.smtp_port
config_master.net.smtp_port = 587
