Have you run
# dpkg-reconfigure exim4-config
yet? (Or equivalent for whatever's sending to it.)

Like exim, CUPS is more complicated as it works both ways. So it may
depend on whether you're running it as a server for a local printer
or a client for a networked printer. The latter has never caused me
any problem when changing the name of my domain. Howver, I haven't
done the former for about a decade, since my HP990 ran out of ink.
That might be more complicated, but I thought CUPS only needed
hostnames as it uses avahi (ie the "proper" use for .local).

I don't see the word "domain" on that page. But grepping for the
old name of the domain has never thrown up many references for me.
After all, software should be using getdomainname(), shouldn't it?

Yep, rebooting will recreate that file anyway, because /var/run is
just /run, and therefore ephemeral.

Cheers,
