techboy -> POP3 - Protocol error. 19 (6.Jun.2007 6:30:48 PM)

For a test situation, we are attempting to disable SSL for the POP3 service in Exch 2007. I've set the LoginType to PlainTextLogin but when I telnet to ther server from an external IP, I get an error after entering Login:

-ERR Protocol error. 19

I cannot seem to fund much documentation on what this error means.
POP3 works fine internally. We have configured ISA 2004 rule to point port 110 to the exchange 2007 server. Below is the return from the get-POPSettings cmdlet.
