Some may have noticed a trend of rejecting emails when there are more than
some small number of messages sent over same network connection stream ?
The RFC 821 didn't state anything explicite about it, but indirectly permits
it. As I recall, RFC 2821 does not say anything explicite either.
Could 2821bis say something ?
There is _no_ limit on number of messages sent over established SMTP
protocol connection. Those receivers that want to limit it are expected
not to loose messages from high-volume email lists that often optimize
things by sending accumulated queue over the established connection.
Could there be some EHLO-response telling that the message transaction count
is limited at the receiving server ?
