Resolve the Apache software and mail server to get my email inbox

I am looking for a freelancer who are expert in linux system admin and mail server. I have got a problem with apache software as it is not working correctly. I have changed the main domain in my account but when I changed the main domain there are alot of things that stop working especially in the "change ip address" the ip address did not show up under my account as it show "unknown", the disk space usage showing "none", the smtp are not working as it show "SMTP Banner Check Reverse DNS does not match SMTP Banner", when I enable and disable the DKIM and SPF in the cpanel as it will show the warnings. I have tried to do the repair for apache but it give me the error: [root@server ~]# /scripts/rebuildhttpdconf info [rebuildhttpdconf] Missing IP for domain [login to view URL], using [login to view URL] info [rebuildhttpdconf] Missing ServerName for domain [login to view URL], using [login to view URL] info [rebuildhttpdconf] Missing port for domain [login to view URL], using 80 info [rebuildhttpdconf] Missing user for domain [login to view URL], using chris0147 info [rebuildhttpdconf] Missing owner for domain [login to view URL], force lookup to root info [rebuildhttpdconf] Missing group for domain [login to view URL], using chris0147 Built /etc/apache2/conf/[login to view URL] OK If you have a full knowledge that you know where the problem is coming from to save you alot of time to search for problem that would be great. And also I want to change the ESMTP Exim address to see if i can get my email reaction to inbox. I have tried 2 different domains to send an email to gmail and my email still landing to spam folder. If you can help me how to get my email to get to inbox with my domain or different domains that will be great. I would be happy to reward you $60 after you complete the project. You must use teamviewer to control on my computer and you must have the expert and full knowledge to know how to get my email to get to inbox without land in spam folder. If you cant be guaranteed that my email would get to inbox, please do not bid. If you have the full experience and know how to get my email to get to inbox I would love to talk to you to see if you can help me. Thanks for your interested!!
