Syntax
typedef enum tagINETADDRTYPE {
ADDR_TO = 0,
ADDR_FROM = 1,

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

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.
