	// useful. Nonetheless, take a look at the 'Associated basic status code'
	// in the SMTP Enhanced Status Codes registry (below), then check RFC 5321
	// (Section 4.3.2) and pick what you like. Stick to 451 and 554 if there are

	// Error message that should be returned to the SMTP client.
	// Usually, it should be a short and generic description of the error
	// that excludes any details. Especially, for checks, avoid
	// mentioning the exact policy mechanism used to avoid disclosing the
	// server configuration details. Don't say "DNS error during DMARC check",
	// say "DNS error during policy check". Same goes for network and file I/O
	// errors. ESPECIALLY, don't include any configuration variables or object
	// identifiers in it.
	Message string

	// If the error was generated by a message check
	// this field includes module name.
	CheckName string

	// If the error was generated by a delivery target
	// this field includes module name.
	TargetName string

	// If the error was generated by a message modifier
	// this field includes module name.
	ModifierName string

	// If the error was generated as a result of another
	// error - this field contains the original error object.
	//
	// Err.Error() will be copied into the 'reason' field returned
	// by the Fields method unless a different values is specified
	// using the Reason field below.
	Err error

	// Textual explanation of the actual error reason. Defaults to the
	// Err.Error() value if Err is not nil, empty string otherwise.
