Subject: [9fans] Mail exchanger

I hate to ask this type of question, but I have resolved in my own
fashion too many different misunderstandings between me and Plan 9 and
I wonder if this last one is not the result of a bad guess on my part.

Briefly, I want my freshly installed server to operate as a mail
exchanger.  So what's hard about that?  Well, it's dual-homed and that
seems to add an entire dimension of problems.  Here is a checklist
that requires some input:

	/lib/namespace - add "bind #l1 /net.alt; bind #I1 /net.alt"
			 for the second ethernet card.

	/lib/ndb - create internal and external databases.  I don't
		   quite grasp how to discriminate between them,
		   I'm merely extrapolating that "local" as used
		   in the documentation actually represents whatever
		   the target of the -f option happens to be where
		   one can specify an alternative.

Then, what in fact fails is smtp (I think), together with DNS?
Somehow I don't figure I've explained to either of these quite how to
deal with the two interfaces, so perhaps someone with the right
experience can point me in the right direction or, at least, make
suggestions at what mistakes I may have made.

Basically, I can't figure out how SMTP would know how to determine how
to deliver mail so I am not surprised, only disappointed that it says,
in the queue directory:

	smtp: no route (net!hivemind.net)

Something for the wiki, definitely.
