Is there a way that I can access somebody’s BCC list when they send me an eMail?
I'm afraid you can't. Not disclosing the recipients is the purpose of BCC, hence 'Blind Carbon Copy'. The recipients are not supposed to find out who else received the eMail and the information is not included in that eMail.
The only way to find out would be if you had access to the computer or eMail account the mail was sent from. You would look into the Sent folder, find that eMail, and then find the recipients listed in the BCC field. That would likely involve illegal activity, though.
Thanks Tina for your response, I did think as much but who knows what is possible`in this ever changing world
It's good you asked. Many people are not aware that BCC even exists. :)
