Google Voice forwarding mms to email??

This is my first post here, but I basically caught my Google Voice number forwarding a picture message to my email from an address that contained my voice number, some more numbers, and ended in @txt.voice.google.com. People have attempted to send me pictures before with no success. Is this something new, or am I just really far behind the 8 ball on this one?

ps: body of email read MMS received and a plain text with the same message was sent to my Voice inbox (sans the pic of course)
