Yes, anyone should be able to send mail to users in my
domain, that's right... but the problem is with the
"jokers".
i.e. one valid user, user1, want's to send a fake mail
to user2. He could create one fake account (user3)
from my domain in his MUA (evolution, kmail, etc...),
and not use authentication for smtp.
He could send without problems a mail from
[EMAIL PROTECTED] to [EMAIL PROTECTED]
That is what it seems to me. Can be avoided that?
