exim4.conf.template is completely unmodified from stock mantic.
Bug can be replicated by:
1. Installing mantic
2. Installing exim4 and spf-tools-perl
3. `dpkg-reconfigure exim4-config` and make it accept mail
4. Adding CHECK_RCPT_SPF = true to /etc/exim4/exim4.conf.localmacros
5. Sending yourself an email from Gmail or Outlook and checking the spf header
