Email Verifier is a simple Go application that checks the presence of DNS records for a given domain. It verifies the existence of MX, SPF, and DMARC records and prints the results in CSV format.

• Verifies the existence of MX records.
• Checks for SPF records and retrieves the SPF record if it exists.
• Checks for DMARC records and retrieves the DMARC record if it exists.

• Go (version 1.13 or later)
