Hmmm.... or perhaps the one that logged this:

But when grepped was in the dovecot indices, but not in the fs:

conducive# grep -r 449714DD.4080500@???
/data/mail/conducive.org/wbh/Maildir/
Binary file
/data/mail/conducive.org/wbh/Maildir/dovecot.index.cache matches

..... and after several minutes of head scratching and
searching was found to match the 'marc@???' entry in the
Mozilla Mail MUA 'Idiots' filter, which had deleted it, unread.

*Sigh*... "Irish Alzheimers"

But I s'pose one could add get the effect Marc wants by piping
/dev/urandom to a script that could add headers, then modify them?
