    Re: MTADATA directory

    Here you go:

    The MTA uses a folder named \EXCHSRVR\METADATA to store the MTA database. Rather than using an EDB file, the MTA database consists of a series of files named DBxxxxxx.DAT, where the xxxxxx represents a six digit hexadecimal number. These files are designed to hold messages in transit. Basically this means that each DAT file holds a message that the MTA has accepted, but has not yet delivered. After a message has been delivered, its corresponding DAT file is truncated to one byte. This operation indicates to Exchange that the DAT file can now be reused by another message. This reduces the overhead caused by constantly creating new DAT files, thus improving performance. New DAT files are only created when the number of existing DAT files are insufficient for all of the inbound messages. Each DAT file is referenced by the MTA queue. If any of the DAT files become corrupt, it can cause the entire queue to malfunction.
