DatatypeNot PIIcategoricalDraft
This record is a draft: it has not been reviewed yet and may be incomplete or wrong. Do not rely on it for compliance decisions. Help improve it (see CONTRIBUTING.md).
Three-digit code with which a mail server answers an SMTP command (RFC 5321), as in 250 for an accepted command and 550 for a rejected mailbox. The first digit gives the kind of reply, from 2 for success to 5 for a permanent failure. Mail server logs and bounce messages store it, often together with the enhanced status code (smtp_enhanced_status_code). HTTP and FTP codes have the same form, so use the field name or context.
