It looks like UW imapd with plaintext password authentication enabled and
with the normally-disabled NETSCAPE_BRAIN_DAMAGE feature enabled.

It advertises support for Netscape-proprietary features.

About 12 years ago, Netscape came out with an IMAP client that had a
"Manage Mail" button. If you have an open-source IMAP server and one of
your users clicked this button, Netscape would throw up an error panel
declaring that your IMAP server is "deficient" and needed to be replaced
with Netscape's proprietary server.

There is quite a bit more to this story.

The countermeasure was to implement the proprietary feature in a way that
clicking the "Manage Mail" button would put the user into the download
page for a non-Netscape IMAP client (Pine, Outlook Express, etc.). It's
been many years since this was necessary.
