Set this in the Options across the board:

Tools > Options > Composition > General

There you will see a setting:

Forward messages:

Change from As Attachment to Inline.

If you’ve set yourself to view all headers when reading emails then you’ll see all the headers thrown into the inline view. Change that if you don’t want or need to have such a verbose dump when forwarding emails.

Zakaj ?

Najbolj mi je všeč preprost pregled ob tem pa je še OpenSOURCE.

Dodatki ?

- Minimize to tray (tray način oziroma miniziranje)

- Črkovalnik za slovenski jezik

Ocena ?

Priporočam uporabo za domačo kot tudi poslovno.
