If you got it - this is a good time to stop and ponder how it all worked. You've gone through setting up a lot of services. Look at the diagram at the top of the page - which services have you set up?

Finally we'll set up the IMAP server so we can read email. The way we've set it up - all the email for anyaccount@yoursenecaid.org should end up on vm3. We will set up Dovecot (with IMAP, IMAPS in a later lab) to get easy access to that email.
