We have experience up to about 10,000, and delivery is slow under the
best of cases.  There's a product you can use with Majordomo, called
"bulk_mailer" (or something like that) that sorts outgoing mail by
domain name, so you end up sending less discrete emails; it speeds
things up quite a bit.

But Majordomo is NOT designed for lists this large; there are better
choices; since this is NOT a cobalt-specific issue you my write me
offlist to continue this correspondence.

(And, just for general knowledge, you're going to need very specialized
hardware for decent results with large lists; certainly Sun Cobalt RaQs
and Qubes are NOT designed for optimized bulk email sending.)

Questions/issues on Majordomo should be posted to majordomo-users... the
