We have an ES2000 SP1 and a W2K SP2. We've got an SMTP connector
installed with an address space *, this connector use dns to send
If we sent a mail to whatever address we like it works, also internal
mail doesn't give a problem. Now if the customer on that server try
5.1.8. Stating that the person coldn't be found in the organization
and probably moved to another one.
So what I've tried also to do is make a second SMTP connector with
businesssolutions.be in the address space and told the connector to
deliver the mail to a smart host (mail.businesssolutions.be - which is
the actual SMTP server for that domain) but it still doesn't work
after restarting all the ES services.
Now we added a second ES2000 + W2K for another organization that is on
the same physical network we also created the AD schema but completely
standalone. So we created a new forest also with a new ES
organization. The strange thing is is they want to mail to the
external email addresses of the first organization they get an NDR
5.1.8 also. When the first organization mails to the second again the
5.1.8 NDR appears.
It's a very frustrating error and I can't seem to find anywhere on the
net, nor the ms website, a document concerning the error.
If somebody has this error also or knows a solution please contact me
so we can combine our forces.
thx and regards!
