Method Details
-
isNegativePermanent
public static boolean isNegativePermanent(int reply) Determine if a reply code is a negative permanent response. All codes beginning with a 5 are negative permanent responses. The SMTP server will send a negative permanent response on the failure of a command that cannot be reattempted with success.- Parameters:
reply
- The reply code to test.- Returns:
- True if a reply code is a negative permanent response, false if not.
-
isNegativeTransient
public static boolean isNegativeTransient(int reply) Determine if a reply code is a negative transient response. All codes beginning with a 4 are negative transient responses. The SMTP server will send a negative transient response on the failure of a command that can be reattempted with success.- Parameters:
reply
- The reply code to test.- Returns:
- True if a reply code is a negative transient response, false if not.
-
isPositiveCompletion
public static boolean isPositiveCompletion(int reply) Determine if a reply code is a positive completion response. All codes beginning with a 2 are positive completion responses. The SMTP server will send a positive completion response on the final successful completion of a command.- Parameters:
reply
- The reply code to test.- Returns:
- True if a reply code is a positive completion response, false if not.
-
isPositiveIntermediate
public static boolean isPositiveIntermediate(int reply) Determine if a reply code is a positive intermediate response. All codes beginning with a 3 are positive intermediate responses. The SMTP server will send a positive intermediate response on the successful completion of one part of a multi-part sequence of commands. For example, after a successful DATA command, a positive intermediate response will be sent to indicate that the server is ready to receive the message data.- Parameters:
reply
- The reply code to test.- Returns:
- True if a reply code is a positive intermediate response, false if not.
-
isPositivePreliminary
public static boolean isPositivePreliminary(int reply) Determine if a reply code is a positive preliminary response. All codes beginning with a 1 are positive preliminary responses. Postitive preliminary responses are used to indicate tentative success. No further commands can be issued to the SMTP server after a positive preliminary response until a follow up response is received from the server.Note: No SMTP commands defined in RFC 822 provide this type of reply.
- Parameters:
reply
- The reply code to test.- Returns:
- True if a reply code is a positive preliminary response, false if not.
