I agree entirely; however in practice that doesn't always happen, because
of faulty MUAs and faulty MTAs which don't report back SMTP level error
messages, especially if it is a multi-line response.
Even when they do, they are buried in a page of unintelligible MTA
tech-speak that end users just don't understand - their eyes glaze over.
Here, I'm probably going to alter my SMTP reject messages to contain a URL
on the first line which points to an appropriate page. At least this will
be useful for those who have the courage to wade through the tech-speak to
look for something useful, and may also get through to those whose MTA
only reports the first line of a rejection message. I can't help much for
those lumbered with an MTA that reports back little more than "it didn't
work, Error 0xF0ADF0AD".
That being said, I don't feel I am responsible for the failings of such
systems, so I don't let it worry me ...
