Whenever a message is received Wild Duck parses it into a tree-like structure based on the MIME tree and stores this tree to MongoDB. Attachments are removed from the tree and stored separately in GridStore.


# Optional database name or connection url for GridFS if you do not want to
# use the main db for storing attachments. Useful if you want
# to use a different mount folder or storage engine
#gridfs="wildduck"
