Another good solution is 'splitlist':

    http://www.isf.ru/~stas/splitlist/

This page says, among other things:

| Q.: Many of the Majordomo users asked me, why I didn't use bulk_mailer ?
|
| A.: First, I didn't know about it at all. Second, bulk_mailer uses
| sendmail command line instead of SMTP, and this means it can't
| decide properly whether to fork sendmail, or just put the message in the
| queue. While talking via SMTP, Sendmail checks the system load and
| makes decision - to fork or not to fork.

One thing I didn't like about splitlist is that you had to set the
number of recipients per message globally in your majordomo.cf,
so I changed it to calculate this figure on the fly using a new
variable ($numSplitlistChunks) and the number of recipients on the
list currently being split. If anyone wants my changes, let me know.
