Exim Message-IDs and spool files
The message-IDs that Exim uses to refer to messages in its queue are mixed-case alpha-numeric.
Files in /var/spool/exim/msglog contain logging information for each message and are named the same as the message-id.
Files in /var/spool/exim/input are named after the message-id, plus a suffix denoting whether it is the envelope header (-H) or message data (-D).
