Don't use a dn_ channel, that will not run the correct channel program.  You
need to use a "d" or "d_" channel for this.  A "d" channel is normally used to
support DECnet MAIL-11 for remote DECnet nodes that do not have PMDF.  It turns
out that PMDF supports remote DECnet MAIL-11 nodes simply by handing the message
to VMS MAIL, which makes the network connection and does the transfer.  If
the address has no remote node then this devolves to being the same as a local
VMS MAIL delivery -- hence the use of a "d" channel for alternate local
delivery.

If you are already using a "d" channel and you don't want its configuration to
change for this purpose, go ahead and create a "d_headers" or something channel
(everything after the "d_" can be whatever you like).

The "mail_" channel didn't work because these channels are used to support other
foreign mail transports through VMS MAIL.  PMDF unconditionally takes whatever
follows the "_" in "mail_xxxx" and puts it in front of the address with a
percent sign, leading to "xxxx%address".  In your case the foreign transport
prefix didn't match an existing foreign transport, therefore the error.
