My email service provider blocks mails with attached .eml files, apparently for security reasons, with the result that I loose relevant mails.
I have tried to find a description of the current security risk of forwarding mails with .eml files attached, but I could only find posts about 10 years old about vulnerability in Outlook.
What are the current risk of mails with .eml attachments, and is blocking by an email service provided still relevant ?
