The standard answer to this question is, "Install Sendmail 8.x
because it does all the sorting, grouping, etc. that you can
imagine". Huge mailing lists suddenly use much less bandwidth
because of all of this.
If you have done this and are still seeing problems, ask your
question again with more details.
