 They seem to be a bit slower, but there's enough variability among the
replies that it's hard to tell. I see an occasional 1000ms when the Mac
is on, but when it's off I see some mid-3figure ms times. So that's hard
to judge.

This was at the beginning of the thread. I since upgraded to F19 but the
problem continued.

Yeah--for some reason I started this account using the one address and
unfortunately forget to stick with that one.

I got a nice off-list reply from Pete Biggs that's helping me understand
how packets returning from mail.researchintegration.org might be getting
misdirected. Seems maybe my router may be having trouble identifying
which packets from my mail server should go to which host. Which seems
strange, since surely different hosts on a NAT'd LAN communicate with
the same remote mail server all the time, don't they? So I think my next
step is upgrading my router--I have a "new" one, but it's apparently not
a recent model (Netgear WPN824N).

Thanks.
