Hi Zube, I've also noticed an issue similar to this. Some abuse reports we get go through a Google Apps domain. I've noticed receiving an initial abuse@ sample through google apps works just fine and the message is delivered. However, if I reply to that email, or if I forward it along, Google gives me a bounce back message stating they can't send the message b/c it's spam. Only if I remove the previous content entirely can I reply to these emails. This does not seem to effect the initial messages delivery, only when I reply/forward the email will Google Apps let me know the message cannot be delivered.
Unsure if this is exactly related to what you are bringing up, though it sounds similar and it's a change I've noticed in the last 2-3 weeks.
