Depends on the receiving MTA and configuration. A 550 is a rejection for "mailbox unavailable" reasons. Those could include a nonexistent address, but also other causes. sendmail will issue that particular 550 message string on a DENY hit in access.db. Some MTAs/configurations will issue it to obfuscate the exact reason, which might be a funky HELO command or a failure to reverse lookup the inbound MTA's IP address.
