The mailman.mc file (cited in README.mm-handler) mentions this vaguely.
If the "m" flag is not present in the mailer definition (the "M" line)
in sendmail.cf, then mm-handler will be run once per recipient.

It's important NOT to have an "m" flag, but just in case you forget
that, mm-handler tries to handle multiple recipients a little.
