Thanks.  I was poking around the wrong files.

I thought that debian's exim4 read the files under /etc/exim4/conf.d/, and if I edited them, then exim4 would behave with their settings.  Turns out exim4 reads config.autogenerated in /var/lib/exim4/ and after editing the files in /etc/exim4/conf.d/, you have to do `update-exim4.conf` to regenerate the real conffile.

Works now after I edited /etc/exim4/conf.d/main/01_exim4-config_listmacrosdefs to include my gateway's ip from `ifconfig ppp0` and did `update-exim4.conf`.
