MailCheckr is a simple Go-based CLI tool that checks a domain's email configuration by verifying the presence of MX, SPF, and DMARC DNS records.

• Checks if a domain has MX records (used for receiving emails)
• Extracts and verifies SPF records (used for sender policy framework)
• Looks for DMARC records (used to prevent email spoofing)
• Outputs a clean summary of each domain's email DNS status

Make sure you have Go installed on your machine.

git clone https://github.com/rajanarahul93/MailCheckr.git
cd MailCheckr
go build -o mailcheckr

./mailcheckr

You'll be prompted to enter domain names one by one. Press Ctrl+C to exit.
