remember... HPT is the one using only those fields... other tossers use a
CRC of the header or the header and the body or even the header plus the
first 40 or 50 bytes (which will get some control lines which also
reenforces the ideal that message contents are not modified in transit like
some tossers that sort control lines instead of leaving them alone) and
they may specifically include the MSGID if it exists... using the message
body is fine, too, if you can spare the CPU cycles to strip out line
endings and possibly extraneous white space characters... using the entire
header is a good thing and is one reason why software should not be stingy
with the time stamp like some are that force the seconds field to :00
instead of using the actual seconds... that limits to one post per second
if seconds are a primary sensor used to detect duplicates... simplistic
duplicate detection methods run afoul of software that can post hundreds of
messages per second... especially if those messages do not have MSGIDs that
do not repeat over a three year period...
