There are a few additional controls that appear only on this page:
Here you enter the POP or IMAP account name of the mailbox on the mail server. This is the account Traction will use to log in to the mail server. Please note the warning in red and do not use your own personal mailbox -- all email in the account will be posted to the Traction space (if the sender has post permissions) or otherwise bounced to the original sender.
This is the password corresponding to the above username. It is stored encrypted in the Traction journal.
This is the actual address to which email should be sent. It will be displayed in user-visible views in order to inform people where to send email intended for this space.
Once all of the information on the page is correct, you can press the Test button.
This will attempt to contact the mailbox and will report success or failure. If the test does not succeed, the error message displayed at the bottom should help you to diagnose the problem.
