Just now, I saw my first Portuguese (Brazillian, likely) email spam come through my gmail account.

I've now recieved spam in the following languages:

• Portuguese (Brazillian)
• German
• Japanese
• Korean
• Chinese
• French
• English

I'm sure there is more; that's just what I remember off the top of my head. Of course, some spam has a language of its own so vile and obscene that it should be repeated in no language known to man.
