Hello Lads.
I am sharing a great security tool to check your health in your email environment.
This tool is provided by the National Cyber Security Centre based in the UK; the goal is only to put your domain. The tool checks SPF, DMARK, DKIM, and TLS.
To verify DKIM, you need to write an email, and NCSC will validate this and send a secure code. Follow the instruction carefully.
Please check and share this tool.
Enjoy!!!!!!
