MX-Record-Checker

Description

A Python utility to check the compatibility and health of MX records of email domains with their mail servers. This script performs an MX record lookup, resolves the MX domain to its IP, and tries to establish a Telnet connection on port 25 to verify if the mail server is active.

Prerequisites

• Python 3.x
• dns.resolver
• socket
• telnetlib

You can install the required packages using pip:

pip install dnspython

Usage

Clone this repository:

git clone https://github.com/kaiserm99/MX-Record-Checker.git

Navigate to the directory:

cd MX-Record-Checker

Run the script:

python check_mx_record.py

The script will then iterate through a list of popular email domains and check each domain's MX record, resolving it to an IP and attempting to connect via Telnet on port 25. The results will be printed on the console.

Customization

You can add or remove domains from the popular_domains list in the script to check MX records for specific email domains.
