long lSenderIdType
);

plSenderIdType or lSenderIdType
Type of sender identifier found by MSMQ. The following table shows the possible values.Value Description MQMSG_SENDERID_TYPE_NONE
MSMQMessage.SenderId is not attached to the message.
MQMSG_SENDERID_TYPE_SID
The default. The SenderId property contains a SID for the user sending the message.

S_OK |
Success |
E_INVALIDARG |
One or more arguments are invalid |
E_NOTIMPL |
The function contains no implementation |
E_OUTOFMEMORY |

Remarks
If the sending application does not want Message Queuing to authenticate who sent the message, it can specify MQMSG_SENDERID_TYPE_NONE when sending a message. This tells Message Queuing not to attach the SID to MSMQMessage.SenderId.
If the sender identifier is not sent with the message, the access rights of the queue must be set to accept messages from everyone.
The receiving application can use SenderIdType to determine what type of sender identifier was attached to the message.
A SID of a local user (a user not logged in to a Microsoft® Windows® 2000 domain) is only valid locally. Even if a local user specifies a SID, it is not sent with the message.
