Bizarrely, this is happening with several receiving hosts -- I'm
becoming more convinced this isn't an issue with my mail server
configuration, but on the other hand it's not an issue I've run into
anywhere else.
After a bit more googling I've tried fiddling with
tcp_workaround_signed_windows as well as tcp_window_scaling, but no joy
-- any further suggestions would be most welcome, although I fear this
issue is rapidly moving away from on-topic for an Exim mailing list.
