Hi,

I've got a reasonably large list which I want to host with majordomo
because I can't afford L-soft ListServ. Although my list is non-profit,
I'm with a commercial ISP and they charge by bandwidth, so I want to cut
the amount of traffic down to as little as possible. It is an announcement
list so speed doesn't matter. Most of the subscribers are concentrated in
a few domains (about 100 subscribers per domain.) 

Jason Tibbitts III advised that I can significantly reduce the amount of
traffic by using Majordomo 1.94.4 + TLB (or bulk_mailer) + Sendmail 8.8.8.
The theory goes that I can batch several messages together, and send one
copy of the message with n e-mail addresses together as one "envelope" via
my MTA. This will reduce the amount of traffic that my list generates by a
factor of n. 

I heard from Jason Tibbitts III that Sendmail 8.8.8 does it by default
(and limits the number of addresses per envelope to 20 (i.e., n=20)) That
means that I can cut my bandwidth use down by 95%. Will bulk_mailer work
just as well as TLB in this case?

Will this arrangement work? Most people I asked said it probably will, but
is there anyone out there who actually used this arrangement? Or is my
question very naive/newbie? :) 

Yours
