[Evolution] 'From' field, how to forbid wrong emails

[mario chiari <ml mariochiari net>]

Hi,

I have the following issue: it happens to me that, when I edit a msg I
received from Joe to write a mail to Tom, the mail is shipped with Joe
in the 'From' field (so it appear as I fakedsomehow a mail from
somebody else). 

Is there a way to configure Evolution as to forbid to ship anyhow any
mail with a value into the 'From' field different from those listed in
my accounts list?

thanks, regards
mario
