Firstly, if an ISP can be described as "large" and has "millions of
users", they are by definition successful, which means running the
whole of their mail system on one machine (ok, ok, I'll be kind, two
machines 8)) isn't really doing their customers any real service.
What happens when the next virus comes out which causes their own
users to flood their servers?
Secondly, this is not really a valid excuse for preventing legitimate
users of their mail system from knowing if their mail could not be
delivered.
