Avast 2014 a bit hyper with spam detection ?

After upgrade to windows 8.1 i needed to reinstall my buyed avast. So i have installed the 2014 version.
But avast get a bit hyper with my e-mails.

When i reply on mailinglist, i also see my own posting back as mail.
And avast is everytime marking that as spam
At least i think its avast becasue not seen it before with windows 8

Please, choose “Not Spam” and also “White list” to teach avast about this.
