Yes -- that is an overstatement. However, the RFCs/STDs covering SMTP take a pretty sharp stand on what an implementation should and must do if it "accepts" a message and then cannot deliver it to (any of the) addressees...
Amen to that. RFC2821 says: 6.1 Reliable Delivery and Replies by Email When the receiver-SMTP accepts a piece of mail (by sending a "250 OK" message in response to DATA), it is accepting responsibility for delivering or relaying the message. It must take this responsibility seriously. It MUST NOT lose the message for frivolous reasons, such as because the host later crashes or because of a predictable resource shortage. Yes. Losing the mail in a system crash is a "frivolous" reason. Harsh. :)
