Hello,
We have seen significant server load caused by Blogger.com users, that post directly to their blogs using the Mail-to-Blogger feature. Unlike the majority of Google applications, Mail-to-Blogger works very bad, the emails require a lot of hours to be sent, as they are not accepted by Google from the first attempt.
Having this said, starting from today, the use of Mail-to-Blogger emails with 123ContactForm is strictly forbidden. We will notify all the Blogger users by email, and they will have 48 hours to set another recipient email for their forms.
Sorry for the inconvenience.
123ContactForm Staff
