I have customized EXIM files that I need installed on one of my servers,
I'll give you the files you only need to install & configure Exim, bind, dkim, spf and 5 IPs.
There are a few files to edit but the instructions are there. You need to create a couple of users and verify that everything match.
I have the files and INSTRUCTIONS already, this is from an old project you only need to follow the instructions and have it done, if you know EXIM you will do it quick.
I would like you to explain me step by step if there is something missing or an extra step I need to know! I'm not an expert in Linux so a clear explanation in English would be great!
We need to test it of course!
