fix Email Deliverability for 3 Domains (SPF, DKIM, DMARC, PTR, Blacklist Removal, Server Security)

Title:
Email Deliverability Expert Needed – Fix SPF/DKIM/DMARC, Blacklist Removal, Server Security (3 Domains)

Description:

I need an experienced email deliverability + DNS + server security expert to fully repair and optimize email sending for three domains:

jewelercart.com

legalcart.net

cashprohomebuyers.com

These domains need to be configured properly for inbox deliverability with Gmail, Outlook, Yahoo, and corporate email systems.

Recently, one of my server IPs was blacklisted and marked as having an open SOCKS proxy, so I also need the server cleaned and secured.

What Needs to Be Fixed
1. Email Authentication

Each domain must have:

Correct SPF

Working DKIM (not currently enabled)

Strong DMARC (quarantine or reject)

Alignment for SPF + DKIM + DMARC

BIMI readiness (optional)

2. Server IP & Blacklist Cleanup

My server IP 104.238.220.190 is listed on:

DroneBL (Open SOCKS Proxy)

s5h.net

You must:

Identify and remove the open SOCKS proxy

Clean any malware or suspicious services

Secure the server

Submit proper delisting requests

Ensure IP stays clean going forward

3. DNS Configuration

Fix/verify PTR (Reverse DNS) → must match hostname

Ensure HELO/EHLO identity is correct

Configure Cloudflare DNS where needed

Set up proper MX records if needed

Verify all DNS changes propagate correctly

4. Deliverability Improvement

Warm-up plan for sending domains

Fix Gmail/Outlook spam delivery

Help test inbox placement

Verify domain reputation recovery

Recommend or configure external SMTP if needed (Moosend, SendGrid, Mailgun etc.)
