Wouldn't it make sense to add the line count field to the index file?
That would solve the CR+LF issue.

And I have another idea, which some time ago saved my butt with Courier:
add a line count L=?? maildir flag, which would make messages look like:

-rw-------    1 root     root         4811 Feb  9  2006 1138386088.22293_0.mail1,S=4811,L=104

(we had to patch Courier to use that)

This flag could be set by LDA or when generating the index. Wouldn't
this solve the issue in an elegant way?
