How to block senders?

[FrankSMS]

I see no place where I can black an email sender. Did I miss something?

You can use a message filter to automatically check whether a new message was sent from a specific email address, and move or delete it. Its best to use "contains" rather than "is" when checking the email address. That works well for a small number of senders. However, to deal with spam in general you want to use the junk mail controls to avoid re-inventing the wheel.
