Linux Server Setup and Maintenance

I have a dedicated server hosted by Liquid Web.

On this server I have several domains active and all but one of them share the IP address of the server.

One of the domains has a dedicated IP. This domain has an EVSSL certificate. The server and other domains share a lesser certificate.

The problem I am having and where I need help right away is with email.

Last week a Russian bot found a form on the website with the dedicated IP and inserted 20000 form requests. This caused 20000 emails to be generated in a very short period of time. Most of those emails bounced because they were phony which resulted in another 20000 incoming messages and another 20000 autoresponses.

As a result Google, Outlook and others now reject emails from that domain. It was a one time thing and we do NOT spam or send newsletter. Never send bulk email at all.

I ran some tests using Glockapps and it appears that there might be problems with rDNS, SPF, DKIM and security.

What I need is three fold.

1. Check the server and domains to make sure the email services are set up correctly and if not to fix them.

2. Help get back into good graces with Google and Outlook, etc. Funny thing is the IPs in question do NOT appear on any blacklists I can find. But Google directs it all to the spam folder or rejects it.

3. Lastly I need someone who is really skilled in Linux and WHM to make sure the server is all setup correctly for the job and as secure as possible from being hacked. I think this could be an initial job with a monthly checkup.

Gif included is from Glockapps scan and is an example of the results.
