Check if an email from mail.com is phishing and report it

Have you received a suspicious email that appears to be from mail.com (e.g. ‘mail.com Customer Service’ as the sender's name) and in which you are asked to take action related to your mail.com account? It is possible that this is not a legitimate email from mail.com, but Phishing, a fraud attempt to obtain your personal data.

This service allows you to have such emails checked for authenticity and report them if they are not trustworthy. To do this, you must upload the email to be checked in EML or MSG format. You will then receive direct feedback based on an automated check. The maximum file size is 8 MiB.

How can an email be saved in MSG or EML format?
