Cand send or receive mail on exchange 2003

I have setup 2 exchange servers that work in different forests in my office as test run. Both are configured the same.And I am testing just one at time over my internet connection. The port 25 is being routed to the right locatrion. One is working good the other is geting error ID290 when I send message anywhere.
The Warning id 290
a non-delivery report(reason code unable to transfer and siagnostic code unrecognised OR name) is being generated for message C=US;A=;Taylorgroup:L=ALL-SRV-01 050507023336Z-9. It was originaly destined for DN:CN=JDUFF,CN=RECIPIENTS,OU=FIRST ADMINISTRATIVE GROUP,0=TAYLORGROUP(recipient number1),and was toredirect to [MTA DISP:RESULT 16 136](12)

Couln't find explanation. Does somebody have answer?
