DeleteMessage Method
Deletes a message from the server-side mailbox.
Syntax
int DeleteMessage(int iIndex);
Remarks
Call this method to delete a message from the mailbox.
Note that the message may not be deleted immediately. It is typical for POP3 servers to only mark messages for deletion upon receipt of this command, and only delete them after the connection has been gracefully closed.
If needed, messages can be "undeleted" during the same session by calling the Undelete method.
Error Handling
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
