Starting yesterday, 16 December 2010, Yahoo decided to return all 276 E-mail Editions sent to our subscribers who signed up with a Yahoo e-mail address.
In the past, we would receive returned messages because we are part of Yahoo’s “spam feedback loop”. This means that if someone labeled the E-mail Edition as junk, we would be notified. We would then promptly remove their e-mail address from the mailing list.
In addition, we received other detailed error messages from Yahoo explaining the reason why our E-mail Edition was rejected for a particular address.
This time, we got: “554 Content not allowed ”.
