Hello,
I am trying to configure SRS under Centos 7 using the perl module. I
installed the perl module using CPAN, and then configured Exim following
this guide:
https://github.com/Exim/exim/wiki/SRS-config-using-Perl-Mail::SRS
But it doesn't seem to do the rewriting.
Here is my /etc/exim/exim.conf:

DKIM_ENABLE = yes
POSTGREY_SOCKET = /var/spool/postfix/postgrey/socket
