SMTPReply

java.lang.Object

public final class SMTPReply extends Object

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.

Constructors Summary

// Cannot be instantiated
Methods Summary
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.
param
reply The reply code to test.
return
True if a reply code is a negative permanent response, false if not.
return (reply >= 500 && reply < 600);
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.
param
reply The reply code to test.
return
True if a reply code is a negative transient response, false if not.
return (reply >= 400 && reply < 500);
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.
param
reply The reply code to test.
return
True if a reply code is a postive completion response, false if not.
return (reply >= 200 && reply < 300);
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.
param
reply The reply code to test.
return
True if a reply code is a postive intermediate response, false if not.
return (reply >= 300 && reply < 400);
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.
param
reply The reply code to test.
return
True if a reply code is a postive preliminary response, false if not.
return (reply >= 100 && reply < 200);
