Steps to reproduce:

I received an email from a friend. This e-mail was also sent to other people than me. I wanted to use this e-mail as a "new message" ("modify as a new message"). But it was not my address that was reported in the "sender" box but the address of one of the previous receiver. I did not realize and I sent the e-mail.


Actual results:

 Everybody received the message like it was not my message but the message of somebody else. Second test : Actually it is possible to modify the "sender box" with keyboard when using the "modify as a new message" option. It can write whatever I want in here.


Expected results:

It should not be possible to modify the sender's address using the keyboard.
It should not be possible to send a message with a random "sender" or a "sender" that is not recorded in any local account.
The name of the owner's account should appear in the "sender" box when using "modify as a new message" and it should not be possible to alter it by typing
