Package: postfix Version: 2.4.0-2 Severity: wishlist The sendmail interface under exim supports restrictions on who can set an arbitrary sender with "-f", enforcing that some local users can only send out mail with their authentic address. It would be useful if postfix had such a feature to prevent local forgery; without it, anti-forgery technology such as SPF or DomainKeys can't be implemented with that much confidence. [EMAIL PROTECTED] could send from [EMAIL PROTECTED] via the sendmail interface, and any SPF or DomainKeys addon would have no way of knowing of the forgery and have to emit/sign the mail.
