this is all down to Debian and nothing to do with Emacs. When you run
apt build-dep it installs all the packages involved in the Debian build
of Emacs. The debian system has a mail daemon specified as a dependency
for Emacs.

All you need to do is just uninstall postfix. It will have no effect on
building Emacs.
