can I block spam emails using my email to send to hundreds of googlegroups.com
I am receiving hundreds of spam emails from gmail.com email addresses and they all say to: and list at least 20 or more googlegroups.com groups. SO it seems they are using my yahoo email to send all these google groups a message to join some dating site. Most all of them go to spam or trash but I want to know if I can block them completely by blocking or using a filter that can block words, or domains like @googlegroups.com. SEE BELOW It only shows my email in the raw message. Your filters only allow me to send them to the trash folder when I would rather block them 100% I have no idea why I am receiving them and not a member of googlegroups and they are using my email to send these through. I can block each gmail but they change every time. I do not know if there is a actual from email I could block that is hid in the raw message but I doubt it since they change the from email.

You need to contact Gmail support for this request since Firefox has nothing to do with Google or Gmail issues.
