Per protocol specification, SMTP is EXTREMELY robust.
It will retry delivery, nominally once an hour, for up to five (or
seven) days. That's 120-168 delivery attempts.
Further, SMTP implementations MUST (RFC sense of the word) deliver a
notification back to the sender if the implementation was unable to
delivery a message.
this queue re-transmission, and failure
notification, can be done with a small python
script.
Will that python script allow for the situation that the message is
received, but the message was NOT safely stored for onwards transmission
before the receiver crashed, and as such the message has not been
SUCCESSFULLY received?
SMTP has lots of things specifically meant to ensure messages survive
the internet jungle on their journey ...
