This is a function of the software (pdflatex) that creates the pdf from
the Tex input file. The actual source is

        MTA = 'Postfix'

with apostrophes. Both the mailman-install.txt file in the tarball and
the HTML in the tarball and online at, e.g.
<http://www.list.org/mailman-install/postfix-integration.html> have
ascii apostrophes

Not necessarily. The outgoing MTA is specified by the
Defaults.py/mm_cfg.py settings SMTPHOST and SMTPPORT and can be
anywhere. There are patches available, e.g.,
<https://bugs.launchpad.net/mailman/+bug/558281> to enable Mailman to do
authentication if required.

The incoming MTA is more problematic. It needs to put the incoming mail
somewhere where a process on the Mailman host (e.g., fetchmail) can
retrieve it and deliver to Mailman. See <http://wiki.list.org/x/17891892>.

IMO, a better solution if possible, i.e., if you can control the 'main'
MTA, is to run an MTA on the Mailman host whose sole job is to deliver
to Mailman the list mail relayed from the 'main' MTA and to relay
outgoing mail back.
