It started in the beginning of November and I cannot see anything wrong with settings I used before, beside there were NO changes made to system settings.
Email is NOT sent out when I post directly to the blogs blog or post using LiveWriter – it only going out when I post new topic into the Google group itself.
Based on this info I think it is a problem with Blogger “BlogSend address” – it is NOT being sent out
(Settings è email&mobile è blogSend Address )
I filed support "question" (Blogger provides NO support) and I saw that quite a lot of Bloggers having the very same problem once in a while.
Brandt from Trade Guild is having the same kind of problem – we working to resolve it, but Blogger is not keen on resolving issues…
Lets hope it'll be fixed …soon
