Many MTA understand these and map them to sensible SMTP error messages.

Inability to find an inbox results in "5.1.1 user unknown".
Misformatted messages are rejected with "5.6.0 data format error".
Unsupported inbox versions are reported as "5.3.5 local configuration error".

All of these are interpreted as permanent failures.
