FILEINTO ims-ms-channel-specific option
ims-ms-channel-specific options: FILEINTO (0 or 1)
FILEINTO ims-ms-channel-specific option controls whether subaddresses are interpreted as folder names for delivery purposes by the channel. The default is 1, meaning that such folder delivery is enabled. If this option is set to 0, then folder delivery is disabled.
This channel-specific option is not normally changed from the default value; but if it is, see also the general
fileinto channel option, with whose setting this
ims-ms-channel-specific option should be coordinated.
