Can Spamsieve detect and delete emails in a foreign language?

Suddenly, about three months ago, I started to receive spam emails in French. Spamsieve correctly puts them in “Spam”, but is there a way that they all be put into “Trash”, without me having to do anything? I don’t have any contacts who write to me in French!

There’s no built-in way to do this, but you could for example create blocklist rules that match some of the common words. If you use the Example 1 setup here, the blocklisted messages would then go directly to the trash.

Thank you for this very quick reply. I’ll try your suggestion with some specific French words.
