Subject: Optimising mail to many recipients

Suppose you need to send a large e-mail message, maybe with
a one megabyte attachment, to ten recipients on another
continent. It might then be much more efficient usage of
the long-distance cables, if you connected to one SMTP
server on the other continent, and sent one copy of the
message, asking this server to forward it to the ten
recipients.

Until about a year ago, this could be done using almost any
SMTP server. But I do not think it was very commonly used.
Is the optimisation not worth the effort? Or are those who
can do this optimisation not people who would benefit from
it?

About a year ago, most SMTP servers all around the world
changed their policy, so that they only accepted messages
to or from their local users. The reason for this change
was to make spamming more difficult.

Does the drums standard say anything on this issue?
