It's only mail to address@hidden that was stuck. That mail is
configured to be forwarded to address@hidden via

But exim on internal didn't know that was its own

In fact someone (in 2011) had hardcoded the old hostname of that machine in
/etc/exim4/exim4.conf.template... The proper way for a simple exim setup like
this would have been to use dpkg-reconfigure exim4-config and tell Exim its
local domain. 

I removed the hardcoded hostname, updated /etc/exim4/update-exim4.conf.conf
(which is what dpkg-reconfigure exim4-config does), and redelivered the
frozen messages.
