It's a sendmail fault. It shouldn't have given 2 messages the same message
ID. Later versions of sendmail solved this problem by completely changing
the way they allocated message IDs so it cannot now allocate the same
message ID twice in less than about 60 years.
Never seen sendmail do this one before...
