PMDF detects encoded messages automatically and is capable of decoding and delivering them as foreign format messages to VMS MAIL. Automatic decoding saves time since the user no longer needs to extract the message, edit it, and run it through a utility such as PMDF DECODE to obtain the contents.
foreign channel keyword enables this processing; this
keyword is only effective for OpenVMS systems and only on the local (l)
channel, the DECnet MAIL-11 channel (d), and mail_ channels. The
noforeign channel keyword disables the use of foreign
format messages, and is the default for all channels. Note that this
default represents a change from the default behavior of versions of
PMDF prior to V5.1.
