All of this emphasis on complex designs for MLMs strikes me as a waste

That's why my advice is that lists should sign their mail, which is
easy and at worst harmless, and we're done.

According to Murray's definition, MLMs include ESPs and email
marketers, which originate a volume of traffic and have historically
been a vector for abuse.  Indeed, except for subscription mechanisms
and deployed software, most of the problems are similar.

It may be productive if we distinguish between two-way discussion
lists where participants send mail to the list, and one-way broadcast
lists where only the owner (or their agent) sends mail to the list.

The difference between these is to be large enough that the concepts
do not generalize that well.

Since I work for an ESP, I agree with this statement.
