Yes, Exim on master.d.o is currently set up to verify envelope senders. It doesn't verify header senders (although such a thing is also possible). The two addresses may differ. So currently the situation is that if your Amazon order or whathaveyou comes in with a deliverable envelope sender address, but an undeliverable header sender address, it'll go through. (More often than not, however, mails come with both addresses being the same.) -- 2. That which causes joy or happiness. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
