Validate Email Code

A Python script to bulk validate email addresses using format, DNS, and SMTP checks.

Description

This project provides a simple yet powerful email validation tool that reads email addresses from a text file and validates each one through multiple verification methods. It checks email format, DNS records, and SMTP server responses to determine if an email address is valid. Results are separated into two output files for valid and invalid emails.

• Bulk email validation from text file input
• Multi-layer validation (format, DNS, and SMTP checks)
• Progress bar visualization using tqdm
• Automatic separation of valid and invalid emails into separate output files
• Configurable timeout settings for DNS and SMTP checks

Technologies Used

• Python 3
