In theory, you could check all the Received headers on each message to
see whether there were unusual delays on each part of the journey, but
the problem with _that_ is that the clocks on each server might be well
adrift. (For example, the arrival times for each hop of Joe's original
message appear to be 2258-2302-2326-2329-2305-2313, which suggests I
received it before did! Hmm.)

If examining those shows that messages from particular people are more
delayed than others, then perhaps somewhere between and
you a mail server is running greylisting software in an attempt to
reject spammers, and forcing to retry later. (Mind you,
in my ISP's case, the greylisting wouldn't delay messages from more than once a day, regardless of who originally sent

All 12 messages in that thread arrived at my box in exactly the order
they were sent, so I don't think can be responsible for
what you're seeing.
