A likely explanation has been sent to you but you haven't responded.
Because WO uses "smtp" as the default SMTP host, it is likely that
"smtp" resolves to the actual SMTP host used by the 2 Macs that work
whereas it doesn't on the Mac that fails to deliver mail. The simple
way to determine this was suggested: at a shell prompt, enter
"nslookup smtp" on all 3 Macs and see what's reported. Let us know.
Sorry Art, I thought I had sent the response below to the whole list.
It details the nslookup smtp result.
I've had an impressive amount of help on this and I've been kept busy
sending replies to all the helpful people, while trying to get it
working at the same time. You guys have done a great job is sorting
this for me. Now I'm trying to make contact with the ISP.

In your development mode it appears that WO is sending mail using the
default smtp host name. If you open terminal on the system where it is
working and type "nslookup smtp" or "nslookup mailhost" does it return
the ip address of a real machine. My bet is it will, and that machine
is an smtp host that will allow relaying of mail from your test
machines. If you do a "nslookup smtp" on you ISP deployment machine my
guess is you will get nothing. That would explain why it works on one
network and not another.
Brilliant! Thank you
on my home machine I get (with some names and IP numbers changed to
protect the innocent)
[iMac:~] denis% nslookup smtp
Server: rachel.myisp.net.nz
Address: 123.96.152.4
Name: smtp.myisp.net.nz
Address: 123.96.152.32
[iMac:~] denis% nslookup mailhost
Server: rachel.myisp.net.nz
Address: 123.96.152.4
*** rachel.myisp.net.nz can't find mailhost: Non-existent host/domain
On the other server I get:
[server4:~] fred% nslookup smtp
*** Can't find server name for address 122.89.39.192: No response from
server
*** Can't find server name for address 122.89.39.28: Non-existent
host/domain
*** Default servers are not available
[server4:~] fred% nslookup mailhost
*** Can't find server name for address 122.89.39.192: No response from
server
*** Can't find server name for address 122.89.39.28: Non-existent
host/domain
*** Default servers are not available
So I now need to get onto the ISP where the server is hosted and ask
for an SMTP name that allows open relay, and ask them why they didn't
give is a simple name that beginners could find without even knowing
they were asking.
Thank you all for your time.
