This is not similar to Are .eml attachments a security risk? as the .eml
file doesn’t any attachment.
My supplier has some email issues he is sending so I sent him the .eml
files to check it. Even I am doing him a favor he says that he is not going to view the .eml
files with a viewer due to security risks and I have to understand it.
My questions:
- Is there any know security issue viewing an .eml file by a viewer, e.q. not in Outlook?
- Or, what can theoretically happen when the
.eml
file is viewed by any external viewer?
The .eml
files I would send are generated by my Exchange based on emails he sent me and do not contain any attachment.
