[Dovecot] APPEND command truncates message

Hi,
I have been debugging a small perl script (see ShowBug2) that I use. In
doing so, I think that I may have uncovered a problem with the dovecot
IMAP server.
Attached are two packet traces for connections to two different IMAP
servers. On both servers I run the script: i.e. I login, select a
folder, search for messages and append a message. On the fvs5 server
(Courier IMAP?), everything works as expected. However, on the dovecot
server, the message that is saved into my mailbox has been truncated at
the end of the line containing "26". I attach a copy of the saved
message in MessageAsOnIMAPServer.txt.
I hope that this report might be useful. Please let me know if you
require any further information.
Chris.
