Receiving database payload

End user/application	VersaLex
End user reviews settings in the VLOptions and VLMailboxes tables.
	With each new incoming payload request, VersaLex checks `VLMailboxes` table `ReceiveIncoming` column to see if trading partner’s `Host`\`Mailbox` is set to receive database payload.
	If database payload, VersaLex inserts into VLIncoming table `TransferID`,`VLSerial`, `MessageID`, `Fileindex`, `Payload`, `Filename`, `ContentType`, `Filesize`, `Host`, `Mailbox`, and `InsertedDT` columns.
End user application polls VLIncoming table for new incoming payload Note: Payload should not be retrieved from the VLIncoming table until the corresponding VLTransfers table row no longer has a `Status` column value of `In Progress`. Valid payload will be indicated by a `Status` column value of `Success` or `Warning`. A `Status` of `Error`, `Exception` or `Interrupted` indicates that payload was not successfully received. The VLIncomingProperties table contains additional payload parameters/headers not already contained within the VLIncoming table, for example, `Subject`.
End user application either deletes row from VLIncoming table after retrieving payload or sets the `RetrievedDT` column.
