Can you pinpoint the exact RFC& section you're referring to? Thanks.
I will give you as home work to study the following documents:
RFC 821
RFC 2821
RFC 5321
These have lots of other good stuff about Internet mail.
I had looked at these and couldn't find any specification of the
guarantees - would you mind pointing out what you're referring to?
Thanks, greatly appreciate it.
section 6.1 in both 2821 and 5321:
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.
if you still don't see, focus on the "crashes" part.
