Since noone's mentioned s*ndm**l yet, this seems avoidable.

I've used both and would not mind using one over the other, but...

ezmlm(-idx) is the best MLM, full stop. All other MLMs pale in
comparison. That's one hell of a good argument if you're looking into an
MTA for mailing lists. ezmlm/qmail running under tcpserver under a
softupdate'd *BSD... well... And since this is x-mailed to the postfix
list, where not everyone might be familiar with this document:
,----
| Mailing list management is one of qmail's strengths. Notable features:
|
| * qmail lets each user handle his own mailing lists. The delivery
| instructions for user-whatever go into ~user/.qmail-whatever.
|
| * qmail makes it really easy to set up mailing list owners. If the user
| touches ~user/.qmail-whatever-owner, all bounces will come back to him.
|
| * qmail supports VERPs, which permit completely reliable automated
| bounce handling for mailing lists of any size.
|
| * SPEED---qmail blasts through mailing lists an order of magnitude
| faster than sendmail. For example, one message was successfully
| delivered to 150 hosts around the world in just 70 seconds, with qmail's
| out-of-the-box configuration.
|
| * qmail automatically prevents mailing list loops, even across hosts.
|
| * qmail allows inconceivably gigantic mailing lists. No random limits.
|
| * qmail handles aliasing and forwarding with the same simple mechanism.
| For example, Postmaster is controlled by ~alias/.qmail-postmaster. This
| means that cross-host loop detection also applies to aliases.
|
| * qmail supports the ezmlm mailing list manager, which easily and
| automatically handles bounces, subscription requests, and archives.

I run a few mailing lists (4 of them would definitly count as "high
volume") and where MajorDomo and MailMan were hitting really bad on the
CPU with Sendmail, ezmlm-idx and qmail are hardly noticeable. On a
reasonably fast machine.

Arguable.

Highly arguable.

Unfortunately, also arguable.

I'd say that heavily depends on the MLM chosen.

... per slot. As per usual.
