Email Config Checker

Email Config Checker is a Python script that checks the DNS records for a list of email accounts. The script checks the MX record, SPF record, and DKIM record for each email account and tests the SMTP connection to the MX hostname.

Requirements

• Python 3.x
• dnspython library (pip install dnspython)

Usage

1. Clone or download the repository to your local machine.
2. Rename config.ini.example to config.ini.
3. Open the config.ini file and customize the configuration settings as needed.
4. Run the script by typing python dns_checker.py in the command line.

The script will loop through the email accounts in the email_accounts configuration and print out the DNS records and SMTP test results for each email account.

Example output

Checking email address john@example.com
MX records for domain example.com: ['mx.example.com.cust.a.hostedemail.com.']
SPF record for domain example.com: "v=spf1 include:_spf.hostedemail.com ~all"
DKIM record for email john@example.com: "v=DKIM1;t=s;p=exampleaYCaVwFGAdnQIhDAQAB"
Email address john@example.com is working

Checking email address sarah@example.com
MX records for domain example.com: ['mx.example.com.cust.a.hostedemail.com.']

DKIM record for email sarah@example.com: "v=DKIM1;t=s;p=exampleaYCaVwFGAdnQIhDAQAB"
