exchange 2007 forward to external address

having an odd issue, we are running google apps pilot in dual config mode.  We created a test domain to use for the google mail part of it.  So what i did was created a mail contact in 2007 EMC for my test address and then went into my mailbox and set it to forward to that contact. It works it seems except when i try to send mail from my main account to the test domain.  i get this NDR

I think so mate - if it did work for a short time, it suggests they suddenly decided they didn't like it and classed it as spam.

If you google it, there is a postmaster page for Yahoo with instructions on how to avoid being classed as a spammer and it used to have a request link to be untagged but I don't know if it's there anymore or not.

It might be specific to Yahoo - they can be very very particular about what they consider to be spam.

I suspect Yahoo are the recipients mail host.

Try doing an nslookup on the forwarded domain?

set type=mx

yes that is all correct, as I said, it works outside the organization it gets delivered both places fine, but if i try to email from internally to the forwarding address, i get the NDR...i get that 550 error from yahoo.  It appears they think I am trying to relay.
jasonmichelAuthor Commented:
yeah yahoo small business is the domain provider and they handle the MX, which i believe points to google apps mail server
Tony JLead Technical ArchitectCommented:
So you send an email to your google apps test address from a.n. other account external to your business and it goes through ok, but if you try to send from one of your google apps addresses it gets stopped as spam?

How weird - if anything I'd expect the reverse to be true.

It might be worthwhile getting onto the Yahoo postmaster page to request the domains be unrestricted.
Tony JLead Technical ArchitectCommented:
Yahoo & AOL are both particularly anal about their 'spam' policies and neither really seem to make much sense.
jasonmichelAuthor Commented:
yeah the mx points to  MX preference = 10, mail exchanger =  MX preference = 20, mail exchanger =  MX preference = 30, mail exchanger =  MX preference = 40, mail exchanger =  MX preference = 50, mail exchanger =  MX preference = 70, mail exchanger =
jasonmichelAuthor Commented:
yeah i know aol is always a PITA, yahoo usually isn't too bad, yahoo is horrible about allowing yahoo accounts to send out spam

So is this something maybe yahoo has to fix?
