Well, I would evaluate the average list in the understanding of how BM
works. For instance what does BM does?

Well it takes your whole list and sorts it by domain. Once sorted, it
takes (on standard mode without any maxdomains setting) sublist of 20
different domains, as many times needed to fulfill your recipients
list. So, if you have 10K recipients, and each one of a different
domain, it would fork 500 times. It is not so important how large is
your list but how many domains yoou are delivering to. 

BM once in contact to your MTA and once your MTA establishes
connection to your recipient's MTA will hand on from 1 to whatever
recipients are on that domain. Here is where the efficiency of BM
enhances mail delivery. Perhaps, if all your 10k recipients are from a
several couples of domains, it would be a good idea too decrease the
maxdomains. But if you have thousand domains, it is a good idea to
increase maxdomains in order to not overload your server and run out
of resources. It is a matter of balance.

I don't know, but documentatin included and a small visit to source
code was enough for me. As long as I got it was only a pre-mailer and
not an MTA nor a substitute for any majordomo's program I had no
trouble setting it up. Even when taht info is in a foreign tongue for
me.

Forever is going to start... right now!!!
