I have created a new mail for test and verify. Have sent to OP PM, please send mail from all 4 accounts that I have listed above. I will update it if received. Please write briefly.
Please make sure to verify DKIM signature. Without it any e-mail address can be spoofed.
And I still would say that they don't need to ask for account numbers to be posted publicly or to have this thread at all. Sounds like a lame PR move and now an attempt to have reputable members involved in validating something.
