[Dovecot] USER environment missing

[Ed]

I am new to dovecot, and while I have the pop server running fine, I am 
having trouble with the imap server.

It starts, but when I try to connect, I get an error:

telnet localhost imap
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
imap(??): Fatal: USER environment missing
Connection closed by foreign host.

Not sure where to start on this one. (or what to show you).

I am running under Ubuntu Linux, usiang postfix, fetchmail, etc.. (not 
sure that matters).
