I've noticed a couple of posts previously where mail from *.appspot.com addresses was classed as spam by Yahoo, but they may now be doing this with mail from custom domains too. Has this started happening to anyone else recently?
I'm ten days into an attempt to get my domain whitelisted, but Yahoo keep coming back asking for the IP address of my mail server despite careful explanations about Appengine. I replied to the last one by asking them what the IP address of Yahoo Mail's mail server was - hopefully that will get the concept across! -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
