The DropDirectory and Messages COM classes are concrete implementations of the IDropDirectory and IMessages interfaces, respectively. Instances of these classes are used to access messages stored in the Simple Mail Transfer Protocol (SMTP) and Network News Transfer Protocol (NNTP) drop directories.
The DropDirectory object can be created directly and used to obtain a collection of messages in some folder on the file system using the IDropDirectory.GetMessages method.
The Messages COM class cannot be created directly and is always returned by a call to the IDropDirectory.GetMessages method. Instances are essentially a collection of messages.
