I am currently trying to review an e-mail sent to myself, that could be malicious, or it could not. I would like to create a sandbox environment to review this kind of message (it's more than likely this will be more than a one off activity), and want to know the safest / best way to create this.
I've read some other threads that suggest a VM environment with no network connectivity (How do I safely inspect a suspicious email attachment?) but unsure of how I would then get access to the e-mail in question without downloading it?
Any help much appreciated.
EDIT After the responses below, I implemented the tools mentioned and followed the steps to good effect. I have however found a tool that seems to allow for sandboxing within a browser, allowing me to quickly reviewing suspicious attachments within a safe environment. I run it within a disconnected VM. The tool is called Sandboxie (https://www.sandboxie.com/).
