Actually, I searched for the from address.  It matches Return-Path
except if resent via a mailing list.

I omitted what I considered irrelevant.  Otherwise I'd have put this:

The message I received four minutes earlier was directed to that list
and CC to me:

The former message, a copy of the lost one, is archived here:
http://www.ietf.org/mail-archive/web/asrg/current/msg17083.html
Curiously, the CC field doesn't show there, which can be explained in
many ways, but I cannot think of one that justifies loosing the
message.  I found nothing else in the mail.log, so I guess maildrop
returned 0, or was not called.  The message was not "empty", as it
contained at least the DKIM signature.  dmesg didn't have any log
around that time.  I found no alert from the array driver.  Nothing.

Should I enable maildrop's logging?
