FWIW, I often see similar behavior, but it's hard to pinpoint.

One problem is that "time" is truly relative.  It's hard to evaluate 
the "out of order delivery" issue without a lot of supporting detail.

If you look at the raw message text, you can get a partial clue by 
checking the "received from" lines to see how the time changes at each 
handoff on the message's trip from there to here.  From your msg:

so your mail apparently took about 2 minutes from 'send' to 'receive'; 
and most of that time was spent in the first queue at psu.edu.

Also, while I've seen horrid delays in my mail, I can't always 
attribute it to the .mac address.  Postings to some lists show up 
quickly; those to others seem to take hours (and the behavior seems 
more closely correlated with the list than the time of occurrence).
