Class SMTPCommand

  • public final class SMTPCommand
extends java.lang.Object
    SMTPCommand stores a set of constants for SMTP command 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 SMTP commands, a set of constants such as HELO are provided where the constant name is the same as the SMTP command.
