You could always install Mailman from source on that system, or you
may be able to find a pre-built package that is based on the latest
This is one of the typical problems when using programs from
pre-built packages, because you're totally dependant on the
person/group/entity that creates the packages.
And I'm not at all convinced that "security problems are not a
problem, with Debian" or any other OS, for that matter. Especially
not with an old binary package that is based on old code that is
known to have security flaws.
I help run the Mailman server and the mail servers for python.org,
and we use Debian Linux for the OS. But we don't use any binary
pre-packaged software, at least not for the critical bits like

In part, that's because we provide the news gateway function for this
newsgroup via the mail servers at python.org -- using the same
Mailman server and the same mail servers that are used to host this
mailing list. Mailman is a Python project, after all. ;)
And certainly, addresses that come in from USENET in an obscured
fashion will most likely have their messages thrown away by most
modern mail servers, even if the Mailman server accepts them and
processes them as normal.
So, when you run that gateway, you pretty much always want to use
real addresses and not make any attempt to obfuscate addresses
crossing one way or the other.

There's a limit to what Mailman can do to fix the subject line, at
least in terms of out-of-the-box code.
If you're a Python programmer, it shouldn't be hard for you to add
your own module to the system to handle these things, and to hook
that into the appropriate place in the flow of messages through the
system. In that case, we'd ask you to contribute your changes back
to the project via the Mailman patch page on SourceForge, so that
others may benefit from your experience.
