SIGNALSPAM

Signal Spam is a public-private partnership that allows Internet users to report anything they consider to be spam in their e-mail in order to then assign it to the public authority or professional who can best take the necessary action to combat the reported spam.

This extension allows you to report an unsolicited e-mail from compatible webmails, including Gmail, Outlook.com, Live.com, Yahoo! Mail, SFR, Orange, Free, OVH, LaPoste.net, and AOL.
