INETADDRTYPE enumeration

[INETADDRTYPE is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

Indicates the type of address and Delivery Status Notification (DSN) request.

Syntax

typedef enum tagINETADDRTYPE { 
  ADDR_TO           = 0,
  ADDR_FROM         = 1,
  ADDR_DSN_NEVER    = 16,
  ADDR_DSN_SUCCESS  = 32,
  ADDR_DSN_FAILURE  = 64,
  ADDR_DSN_DELAY    = 128
} ACCESSTYPE;

Constants

ADDR_TO

Indicates the recipient of the message (To, CC, Bcc).

ADDR_FROM

Indicates the sender of the message.

ADDR_DSN_NEVER

Indicates that all DSN should be suppressed.

ADDR_DSN_SUCCESS

Indicates a request for a DSN on successful delivery.

ADDR_DSN_FAILURE

Indicates a request for a DSN on delivery failure.

ADDR_DSN_DELAY

Indicates a request for a DSN if delivery is delayed.

Remarks

The Simple Mail Transport Protocol (SMTP) protocol distinguishes only between a sender (ADDR_FROM) and recipients (ADDR_TO). A DSN request can made by including the additional DSN flags only if the SMTP server supports DSN (RFC 1891) and the transport connected with an EHLO command.
