Mailman has just been removed from Debian/Unstable because it is "obsolete". Why would it be regarded as obsolete and if so what should we replace it with?

Debian-recommended replacement is package mailman3 or metapackage mailman3-full. Personally, I'm not looking forward to that, as GNU Mailman 3.x is IMO a poster-child for Second System Effect. The bug claims the cause of breakage in package mailman is dependency python-dnspython becoming no longer available. That's from this upstream: http://www.dnspython.org/ One notes that upstream did a migration from Python 2.x to Python 3, and I'm pretty sure that's the root cause of the cascade of package removals, i.e., the familiar and current Mailman 2.x versions all work with Python 2.7.x, while Mailman 3 goes with Python 3. -- Cheers, Rick Moen "The first rule of Dunning-Kruger club is rick@linuxmafia.com you don't know you're in Dunning-Kruger club."
