This is called being forwarded 'inline'.

This is called forwarding 'as an attachment'.

Inline forwarded message, depending on the client, will normally include
either the 'Normal' or 'Short' headers, or the 'Full Headers', whichever
is currently selected.

Outlook is a different beast (as usual)...

However, Messages forwarded as *attachments* *always* contain the full
headers, which is why this is the preferred way to forward messages for
forensic analysis.

Forwarding 'as an attachment', which is what the OP said he wanted, is
certainly a form of forwarding...

Not as long as it is done properly, This is how 'Vacation' messages
using sieve works... although I am a total noob when it comes to sieve...
