I sent you the URL in PM.

I checked the files and the mentioned offsets are one line off the next
from_ line. It looks like a content-length mismatch.

They also seem to mix CR+LF and simple LF endings within the same mail.
For example an otherwise CR+LF encoded mail would have a few headers w/o
CR at the bottom inserted (by dovecot?). Maybe the content-length
computation was therefore a few lines off.

I can probably salvage these mboxes by grepping out the content-length
header, but I wonder why the content-length header are off.
