In general, if you're using "update-exim4.conf" and all that stuff, you might
find you're better off asking on the mailing lists specific to your
distribution. The documentation that came with your package will point you in
the right direction.

H=localhost ([193.63.150.187]) [127.0.0.1]
means that the connection came from 127.0.0.1 (and the name of that host is
"localhost"), and that the client on that connection then said "HELO
[193.63.150.187]"). So 193.63.150.187 isn't the IP address, it's the HELO
name.
