RFC2821bis-01 - number of message transactions per connection ?

2007-03-29 03:41:29

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 ?
