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

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?

nslookup
set type=mx
recipientdomain.com

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.

Why spend so long doing email signature updates?

Do you spend loads of your time carrying out email signature updates? Not very interesting are they? Don’t let signature updates get you down. Let Exclaimer Cloud - Signatures for Office 365 make managing email signatures a breeze.

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.

Yahoo & AOL are both particularly anal about their 'spam' policies and neither really seem to make much sense.

yeah the mx points to  

domain.us  MX preference = 10, mail exchanger = aspmx.l.google.com
domain.us  MX preference = 20, mail exchanger = alt1.aspmx.l.google.com
domain.us  MX preference = 30, mail exchanger = alt2.aspmx.l.google.com
domain.us  MX preference = 40, mail exchanger = aspmx2.googlemail.com
domain.us  MX preference = 50, mail exchanger = aspmx3.googlemail.com
domain.us  MX preference = 70, mail exchanger = aspmx5.googlemail.com

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.
