we've been looking too for solution to send 50.000 mesg. daily.
Our scenario was Sun Ultra60, 512 MG RAM and USparcII, with 2 disks.
It runs sendmail 8.11 and majordomo 1.94.5.
Releases of sendmail 8.10 and above use multiqueue (to improve performance
you'll need several disks, and put each queue
in a disk).
Our goal is to send the same message (32kb) to all users in less than an
hour. We install to do this "bulk_mailer" to improve
performance and management of majordomo.
During benchmarking, using 'top' we detect that the cpu has not a lot of
work (the processes were 0.14% more or less), so
we conclude that the limitation are not HW. We send the 50.000 mesg. in 2
hours with only one host. Hosts are added as speed is needed (to share the
load that has sendmail to send the messages...).
This test was in a labo environment. Probably in production, host will be
compaq (PIII), with linux, sendmail and majordomo.
We think it's cheaper solution with a high level of performance.

Asunto: Need help choosing the right mlm
Dear list --
I am currently researching different mlm's and am hoping to get some
feedback from you all. I will be running the list off of a pentium III 450
with 512 megs of ram on a 4-meg connection (burstable) running linux. I
need the system to be able to process at least 250,000 outgoing emails a
day. Posting traffic on the list will be limited. It will primarily be for
outgoing emails. It needs to track both unsubscribes and bounces. I am
looking for a cost-free solution, but am willing to consider commercial
packages. I am open to pretty much any solution so long as it runs on linux
:). I'm looking forward to your sugguestionis.
Thanks in advance
