Hi,

The company I work for is going to be hosting some moderately large
mailing lists soon. Right now we're just using majordomo with sendmail on
one of our boxes, but I'm going to be putting together a machine
running FreeBSD-STABLE (3.0) just to handle the mailing lists. The new
list we're looking at adding has around 20,000 subscribers (one way, about
message a day). So, a few questions:

a) Does anyone have any recommendations on the type of hardware necessary?
I don't expect that much CPU power is needed (we'll be using a PII of some
sort), but I figure lots of RAM, 128M or 256M is a good idea for lots of
sendmail daemons doing simultaneous deliveries. Anything else I need to
really worry about?

b) Are there any specific kernel settings that would help, beside sraising
the maxusers a bunch? It doesn't seem like anything /too/ stressful should
be going on. A significant number of simultaneous processes and tcp
connections, but nothing massive.

c) Any tips for speeding up majordomo mailing list deliveries with
sendmail? I've heard bulk_mailer could be very helpful, as it would help
with allowing lots of simultaneous deliveries to different sites while not
having multiple connections to the same remote site. Does anyone have any
experience using bulkmail with majordomo?

Thanks for your help,
