I don't see why.
RCPT TO: <t...@blablafoo.com>
450 4.1.2 <t...@blablafoo.com>: Recipient address rejected: Domain not found
Anyway, as said, this check will only refuse mail for domains that really do
not exist (NXDOMAIN) or don't have an A, AAA or MX record. For cases like
hotmail.org which do exist but are known not to deliver (correctly), you'll
have to manually blacklist them.
