Client shows null Sender & date

I'm using Postfix and Dovecot 2.0.19 and Virtual domains & users
(mysql).  Incoming mail is handled by Postfix and then handed off to
Dovecot LMTP for delivery.  However, the Sender and Date are essentially
null when viewing the email with either the POP3 or IMAP client.  The
logs (below) show this.  I changed the sender and recipient addresses
for privacy.

You can see that Postfix accepts the incoming mail (from
sender at and then the message is handed to Dovecot LMTP.  But
the from=: should be "from=sender at".

Postfix / qmgr has the sender listed (from=<sender at>) but no
sender (from=) is seen in LMTP log output.  My LMTP is setup to use UNIX
sockets, not the INET socket.

Any help is appreciated.
