You need to try to deliver one messages for first-host.com then one for
secondhost.biz down that faked session by talking SMTP. Hopefully, the
different treatment will be seen in the debug output. Maybe you can
help yourself.

/usr/sbin/exim4 -bV 
cat /etc/exim4/update-exim4.conf.conf
cat /etc/mailname

Probably, yes. Maybe the output from update-exim4.conf.conf will give
a clue, and maybe the faked SMTP session.

What does /usr/sbin/exim4 -d -bt magicbrain@secondhost.biz say?
