I got the identical set of email with a different company name. All using gmail accounts. I did some googling on substrings in the email and found the exact same letter with these company names:

Callisto Trading Bv
Lowland Trading Bv
Ciparo Products Trading BV
Strootman Trading Bv
Binio Trading Bv
Omsio B.V

Here is how I think the scam works: They send you checks (fake or for accounts without funds) that will bounce. And they encourage you to wire the money fast. Perhaps the first checks wont bounce to get you confident...then they do and you are out thousands of dollars. I won't even deposit the first check. Even if you wait for it to clear, if it is without funds you may be charged by your bank.
