Clearly written by someone who is not an email admin.
Rule #1: Email delivery is imperfect.
Rule #2: Never rely on email for critical communication, due to Rule #1.
Millions of emails have been lost over time due to spool issues, disk failures, and clueless/careless admins. If you cannot afford to lose a piece of email, then you need to followup the SEND button with a phone call to verify receipt.
Or send via fax (which is also imperfect).
Or use FedEx (which is also imperfect).
I bet there's hardly a person alive who WOULDN'T trade one missing email for a 1000 spam reduction.
Oh BTW, Spamhaus doesn't BLOCK email. They only provide lists of bad-sender IPs. It's up to the receiving admin how the inbound spam filters are configured.
