Because each SMTP connection is only sending to one recipient, that's
why.  If you are using VERP or personalized messages, the messages
really are different as far as the MTA is concerned, and thus each one
must be sent separately.

For personalized messages, this is true at the Mailman stage, and
you'll have to choose: multiple recipients per transaction, or
personalization.  You can't have both.

For VERP, it may be possible to configure Mailman *without* VERP, and
have the MTA do VERP itself.  However, I don't know if you'll be able
to take advantage of Mailman's VERP features (such as for bounce
processing) in that case.  You may need to have a separate system take
care of those features at the MTA level.
