In this case, it's your user 'rjordan' connecting to the IMAP server to
check his IMAP mailbox.  It's nothing to worry about, unless you don't want
your users using IMAP mailboxes.  If you don't, comment out the line for
imap in /etc/services after letting your users know so they can migrate to
POP mailboxes.  I imagine you have quite a few lines in your logs that look
like:

Apr 25 02:22:36 ns in.qpopper[20814]: (v2.53) POP login for "a0130004" at
(user-2ivenfo.dialup.mindspring.com) 165.247.93.248

These are logins to access POP email accounts.  Also, nothing to get worried
about.

The "Host unknown" means that Sendmail could not resolve the host of the
email address that sent to your server and therefore is not going to deliver
the email.  I have no reliable insight into the rest of those lines.
