Savannah provides mailing lists. I don't want to advocate savannah too much, because the site isn't pretty, their interface is sometimes strange, they don't default to https, there are lots of reasons not to like it technically. But it's probably a place where you don't have to expect evils like supporting bundled Crapware. The FSF is behind it.
