I have set Appspot.com and several permutations of this domain as blocked. At least they all go to Junk however this is not good enough. I have to filter through at least 10-20 emails a day from Appspot in my Junk folder. I look through Junk because many emails can land there which are actually legit - so I screen this folder.
I find it difficult to understand why (I am apparently not alone) blocking Appspot as a domain name fails to work. Please respond. Thank you.
