Hello all,
I'm playing with Exim and created a mail server that can accept and send
emails alright. Now, I want to enable SPF checking for every incoming email
so that a Received SPF header is added to these emails. But I can't seem to
figure out a way how to do this.
The doc says SPF verification support is built into Exim if SUPPORT_SPF=yes
is set in Local/Makefile. The support uses the libspf2 library
https://www.libspf2.org/.
But I suppose one can only set this option to yes if he/she is building
Exim from the source. I installed it directly from the ubuntu package (I
imagine libspf2 is auto-installed then) and don't know where the location
of the Local/Makefile is. I am pretty sure this can be done pretty easily
but I have no clue about this right now. Can someone help me in
this regard?
More details on this question are on serverfault.com:

Thanks.
