There are two different ways to set up machines which will send emails. It depends whether the emails sent from the machine will go to internal recipients only, or alternatively the emails need to be able to go to internal and external recipients. Choose which of these applies to you then follow the instructions for that choice.
In this case the machine can be configured without authentication (also referred to as anonymous).
Emails will be sent to internal and external recipients
In this case the machine can be configured to authenticate with a username and password. Use the server names and port numbers below to configure.
If the anonymous method doesn't work for your particular machine, there is no harm in using the second method, with authentication, even though your recipients will be internal. If you use the server mail.webville.net you must authenticate. If you use the server barracuda.webville.net you must not authenticate.
