Ok, what happens is that nowadays exim4 listens on ipv6 by default, see
/etc/exim4/update-exim4.conf.conf:
dc_local_interfaces='127.0.0.1 ; ::1'
But exim4 doesn't nicely failback if the kernel doesn't support ipv6
(EAFNOSUPPORT). This is actually not a hurd bug, but an exim4 bug, which
I'll submit.
That being said, I've commited support for enabling ipv6 on GNU/Hurd, so
the issue will fly away :)
In the meanwhile, simply drop "; ::1" from update-exim4.conf.conf and
voilà.
