Some of the most complex, convoluted and difficult-to-maintain code I have
seen in mail systems involves interpreting responses. One of my favorites,
over time, has been the family of Yahoo "4xx deferred but don't bother trying
again, because you will never succeed" permanent temporary failures.
I have interpreted this as a "let's see if we can run the spammers out of disk
space due to queue bloat from retries that haven't timed out yet" device. It
has been gratifying to see exactly this effect on some senders.
