I'm mailing this from Zmail on a Symbolics system to a local VMS VAX via
DECnet. The local VAX is forwarding it to another non-local VAX which runs PMDF
and is our CSnet server. The Symbolics mail system can't handle addresses to
non-local DECnet destinations so we have to use so-called "poor man's routing"
(i.e., every network jump but the first is encoded as a VAXmail address). The
VAXen handle all DECnet routing. From our Symbolics a CSnet address looks like
where 3077 is the DECnet address of our non-local CSnet server VAX. TSD1 is a
local VAX that the Symbolics namespace knows about. IN% is the PMDF system.
By the way, we couldn't use this sort of addressing until we bugged Symbolics
for a patch that allowed addresses that had quoted strings within quoted
strings. The address parser used to barf on the embedded quoted string and
wouldn't accept a backslash to hide it (it doubled or tripled the backslash).
I'm not sure if this patch was included in 7.1 (or 7.2), so if you need it,
drop me a note.
My normal address on CSnet is firstname.lastname@example.org. The alias that PMDF knows
for that address is TSD1::moskowitz, an account on my local VAX. I've set my
forwarding on that VAX to send all my mail to the Symbolics (AIP1::Len). This
way, when the Symbolics server is down, I just cancel the VAXmail forwarding
and the VAX catches all my mail.
