Unrtesolved recipieint mail forwarding failing with relaying denied error.

Hii

We are trying to forward unresolved email from one server to another. I have done this numerous times and it has never failed until now.

We have unchecked the setting that makes that server responsible for all mail in that address space. We then tried entering both the IP (in brackets) then the FQDN under the smtp virtual adapter to forward all unresolved mail to the following host. We have even gone as far as creating an SMTP connector, adding the bridghead and the smarthost info and every time we get the good old relaying denied error when sending to a none existing account instead of the expected behavior of forwarding the message on to the new server.

The error is Action: failed
Status: 5.7.1
Diagnostic-Code: smtp;550 5.7.1 Unable to relay for

We have a mailbox on the final destination serverthat matches the address that we are trying to email. The frustrating and confusing thing is that the server bounces the unresolved address immediately. There are no local spam or filters in place. All filtering is done externally. Examination of the headers indicate that the bounce is indeed initiated by the server and nothing before it.

Anyone seen this behavior before?

had you removed the server address out of the smtp relay restrictions? If so you will need to insert it in as an allowed host.

iF you mean in the relay settings are where you would check allow host below to relay and leave it blank in order to prevent relaying? If so then, yes we added the local host and enabled that featrure.
