After WWHCN "reclaimed" the 'cnet.windsor.ns.ca' domain, I attempted to
reconfigure 'zmailer' to recognize local delivery of mail to both
'www.cnet.windsor.ns.ca' and 'cnet.windsor.ns.ca'.

I couldn't do it (and wasted a lot of time in the process).

I think I have traced the problem:

---------------------------------------------------------------
On chebucto.ns.ca, (interactive router)
z$ thishost www.chebucto.ns.ca
    %dblookup (thishost www.chebucto.ns.ca) <0>
www.chebucto.ns.ca
z$ canon www.chebucto.ns.ca
    %dblookup (canon www.chebucto.ns.ca) <0>
chebucto.ns.ca
---------------------------------------------------------------
On csuite.chebucto.ns.ca
z$ thishost www.csuite.chebucto.ns.ca
    %dblookup (thishost www.csuite.chebucto.ns.ca) <0>
?=1
z$ canon www.csuite.chebucto.ns.ca
    %dblookup (canon www.csuite.chebucto.ns.ca) <0>
www.csuite.chebucto.ns.ca

Note: logged in to csuite, trying to send mail to macneil@www.csuite...
I get the mail bounced back with:
<smtp www.csuite.chebucto.ns.ca macneil@www.csuite.chebucto.ns.ca 1017>: smtp; 
500 (DNS: no such domain: www.csuite.chebucto.ns.ca)

Of course it should not be attempting 'smtp' delivery of this email.
---------------------------------------------------------------
On wwhcn.cnet.windsor.ns.ca
z# thishost www.cnet.windsor.ns.ca
    %dblookup (thishost www.cnet.windsor.ns.ca) <0>
?=1
z# canon www.cnet.windsor.ns.ca
    %dblookup (canon www.cnet.windsor.ns.ca) <0>
wwhcn.cnet.windsor.ns.ca
z# thishost wwhcn.cnet.windsor.ns.ca
    %dblookup (thishost wwhcn.cnet.windsor.ns.ca) <0>
?=1
z# canon wwhcn.cnet.windsor.ns.ca
    %dblookup (canon wwhcn.cnet.windsor.ns.ca) <0>
wwhcn.cnet.windsor.ns.ca
---------------------------------------------------------------
CS_ROOT/etc/mail.conf is
orgdomain=cnet.windsor.ns.ca
hostname=wwhcn.cnet.windsor.ns.ca
mydomain=cnet.windsor.ns.ca
---------------------------------------------------------------
CS_ROOT/var/mail/db/localnames is
.cnet.windsor.ns.ca
cnet.windsor.ns.ca
mail.cnet.windsor.ns.ca
wwhcn.cnet.windsor.ns.ca
www.cnet.windsor.ns.ca


Solution anybody?
