Are you sure there's not some other DNS-based check involved, such as (not that it would be this specific one) the sender-domain-must-resolve check for spam prevention? Just because sendmail doesn't use DNS to reach the destination MTA doesn't mean it isn't attempting to validate the message via DNS lookups.
