Message Status Constants

[This is preliminary documentation and subject to change.]

There are two sets of constants used to set message status. One set is used for messages submitted to the SMTP service, and another set used for messages submitted to the NNTP service. The set of message properties available depends upon this message type. For messages submitted to the SMTP service, you can alter the message status using the MailMsg object's IMMPID_MP_MESSAGE_STATUS property. For messages submitted to the NNTP service, you can alter the NNTP processing status using the MailMsg object's IMMPID_NMP_NNTP_PROCESSING property.
