SMTPReply stores a set of constants for SMTP reply codes. To interpret
the meaning of the codes, familiarity with RFC 821 is assumed.
The mnemonic constant names are transcriptions from the code descriptions
of RFC 821. For those who think in terms of the actual reply code values,
a set of CODE_NUM constants are provided where NUM is the numerical value
of the code.

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.
reply
- The reply code to test.
- 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.
reply
- The reply code to test.
- 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.
reply
- The reply code to test.
- True if a reply code is a postive 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.
reply
- The reply code to test.
- True if a reply code is a postive 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.
reply
- The reply code to test.
- True if a reply code is a postive preliminary response, false
if not.
