Email Settings

Mail setup

New systems will complain that you need to set the Email server's From address  without which email notification, password resets and ultimately COA deliveries will not work 

Navigate to the Email settings as admin user from the system's Plone setup

On the next page:

Settings

The SMTP server and port for sending emails will default to localhost and 25. It is correct most of the times, if in doubt, consult with your systems administrator. He/she will also be able to say about the ESMTP information that can generally be left empty

For the Site From name use a name that will make sense to the users receiving emails, you lab's name

Site From address has to be a valid email address

Be sure the E-mail characterset  is set to utf-8
