Common questions
How this tool behaves
Can it show attachments?
It lists MIME attachment names, types and approximate encoded sizes; Delivery 1 does not extract them.
Does it verify DKIM or SPF?
It displays authentication-result headers when present but does not independently verify signatures.
Can it read every email?
It handles common MIME, base64 and quoted-printable messages. Unusual proprietary encodings may need a desktop mail client.
Practical examples
When to use it
Saved support email
Inspect From, To, Subject and the readable body before importing.
Suspicious message
