I was able to reproduce it without any effort.
First let me ask the obvious thing.. when you filed the sample message
from my original note, did you spot the fact that the "Subject" line
was split into two lines? You have to recombine the two lines into
one. (Sorry about that). Also, remove the "> " characters and,
I guess, save the "From " line at the beginning (although I just
tested it and it doesn't matter if it's there or not).
Here's what I did to reproduce it:
On the target system:
% rm -rf Maildir
% maildirmake Maildir
% cp bad.tmp Maildir/cur/0000.1111.2222.bad
"bad.tmp" is a copy of that message that I forwarded, starting with the
"From" line, or with the first Received line, doesn't matter. Body of
the message doesn't matter either; I kept all the RFC stuff as the
Now from the source system (and here is a cut and paste of what I just
did, except that I changed the username/password):
% telnet target-system imap

This seems to exactly duplicate the report..
Note: the FETCH response above is wrapped.
Is there something I have got set wrong?
