Ask HN: How to parse BCC from incoming emails? Innovatively or Hacking it?

So from where I research you cannot parse the BCC address off an email in transit (Sendgrid, Cloudmailin, Mailgun... etc)

I am trying to think of another way where you, original@email.com, can BCC content to user@email.com - it auto manually-forwards () to general_inbox@email.com;

Open general_inbox@email.com, you would see FWD: Subject Line from user@email.com

() Manually-forwards would be where the email landed inside user@email.com's inbox. Forwards it with FWD to general_inbox@email.com; However, the cPanel forwarding rules are duplicating the email where from is still original@email.com and not user@email.com....

Working off this, is there some way to still fetch the BCC? Or is there another innovative approach I cannot think of?

Final piece to my app.

Thank you! -Gary
