Configuring SBO Mailer 9.0 in service manager

Hello experts,

Can anyone help me with SBO Mailer configuration? As a part of post-installation activities, I am trying to configure SBO Mailer in SAP service manager, but have no clue about SMTP server and port. In AdministratorGuide there is not much about it. I need more specific guide, specially regarding SMTP server and port.

Thank you in advance.
