who maintains mailman 2.1 for ubuntu 18.04.1?

I installed webmin-virtualmin-mailman and mailman in that order. I
have a problem with the installation and asked on the mailman list and
was referred to the maintainer of the distribution's version. I don't
know a) who that is or b) how to find out (apart from asking here).

Anyone?
