it looks as if the last SA-Exim header eliminated the blank line that
separates header and body.

I'm not sure how the sa_exim processing works, I do not use it for long
time now. Does it see the original spooled message and modifies it?
After this step, Exim does its own processessing, splitting the message
into -H and -D?

I'd see sa_exim as the suspicious. Maybe bad cooperation between sa_exim
and Exim when we use wire format spool files (do we?) or when the
message arrives in chunks. I think, we had some other issues in this

For verification, can you add to some ACL the

    warn    senders = linux-kernel@XXX
            control = no_mbox_unspool

directive? This way the message should stay in the $spooldir/scan
folder, even after scanning. (I'm not sure if this is the way sa_exim
works, it is just guesswork and it could help to identify the issue.)

And as another step, can you disable sa_exim for the linux-kernel mails
(or for all mails alltogether), so we can identify a little bit more
about the issue?

[ HERE THE BLANK LINE WAS EATEN, so Exim doesn't recognize
this as the end of the header section of the message.
