I am using Google Mail for my mails. 

Google got this Smart Label feature. Which marks mails automatically as bill or advertisement. This is my problem. 

I don't know why, but when I receive mails from **forge.typo3.org** they become marked as advertisement. Mails from other redmine instances are marked as notification.

The question is: How can I tell Google Mail to use "notification" label instead of "advertisement" for mails from **forge.typo3.org**?

Thanks in advance.
