I received a work letter recently and i got worried since the header shows the addresses, where the letter was BCC-d. I shouldnt see this, correct? 

Tried to replicate this by sending letters to myself to my different accounts, didnt work (no BCC seen).

I am using WLM 2012 build 16.4.3528.0331, Win 7 32.

Adding screenshot.

"Salakoopia" means BCC

Best Regards
