Email Domain Checker 🌐

This Go program checks email domain information including MX records, SPF records, and DMARC records. It prompts the user to input a domain and outputs relevant information.

Usage 🚀

Run the program:

go run main.go

Enter an email domain (e.g., google.com) when prompted, and the program will display relevant information about the email domain.

Code Explanation 📜

Main Program (main.go) 🧑‍💻

• The program uses the net package to perform DNS lookups for MX, TXT, and DMARC records.
• User input is obtained using bufio.Scanner reading from os.Stdin.
• The checkDomain function processes the domain information and prints the results.

checkDomain Function 🕵️‍♂️

• The function looks up MX records to check if the domain has mail servers.
• It looks up TXT records to find SPF (Sender Policy Framework) records.
• It looks up DMARC records by appending "_dmarc." to the domain and checking TXT records.
• The results are printed to the console in a CSV-like format.
