there is no shortage of evidence on the internet of PIXs' smtp fixup
crap screwing things up all over - typically in the form of making
other hosts have difficulty reaching the "PIXed" MTA or successfully
communicating with it after the connection is established.
remember there was even a thread on here a while back about them.

i think keeping net.inet.tcp.{recv,send}space below 65536 (where
the obsd default is 16384, and every time i've spent a day dinking
with the setting to see if i realize any benefit at all with increasing
it, i find myself choosing to just set it back to 16k) would be enough.
net.inet.tcp.rfc3390=1 strikes me as only pertaining to making the
initial window size bigger than if it were set to '0', but not
particularly pertaining to scaling the window size during transmission.
i'd be inclined to expect that changing these parameters wouldn't
allieviate the issue tho.

tcpdump -ni $ext -Xs1500 port 25 and src host $incoming_testing_host ?
