well,suppose this: if i want to send SPAM to *@aaa.com, it's so easy for me becaust all i need to do is to set my SMTP server as smtp.aaa.com and set my email address as [EMAIL PROTECTED], whenever user xxx is valid or not. that's to say, your email server users with get SPAMs without end.Anyone who's valid to use [EMAIL PROTECTED] will be bothered just becaust the server ACCEPT MAIL ADDRESSED TO A LOCAL RECIPIENT but NEVER CHECK WHETHER THE SENDER IS TRULY VALID.
do you think this is also quite normal? Never do i! what i DO EXPECT is:instead of checking whether the sender's address is @aaa.com, the SMTP server will examine whether the sender using [EMAIL PROTECTED] is valid or not. this is called a true authentication.
