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.
The point is, their IT claims they are not going to open the
.eml
files with a viewer. They don't have Exchange so they need a viewer. And this is what I don't understand why viewing an.eml
file with a viewer should be a security risk. – Al Bundy – 2020-01-17T21:17:07.863If that's the problem, can't you export it to .html or something? That does not require anything. – LPChip – 2020-01-17T21:22:34.570
This doesn't answer my question. I am doing him a favor to sending him his emails back to check it and their IT which causes the issue just says We don't open the eml files because of security risks. Thank you for your understanding. Why should I bother with exporting/converting to PDF when they don't move a bit? So, my question is: Is there any security risk viewing an .eml file with an external viewer? – Al Bundy – 2020-01-17T21:26:02.250
My answer is If you trust the sender, then no. Their IT is just stupid. – LPChip – 2020-01-18T10:36:39.383
