GMail OAuth2 BCC error

Hi!

When adding a BCC address, the GMail service reports an error:

Header: Cache-Control=private

Content: {
"error": {
"code": 400,
"message": "Invalid Bcc header",
"errors": [
{
"message": "Invalid Bcc header",
"domain": "global",
"reason": "invalidArgument"
}
],
"status": "INVALID_ARGUMENT"
}
}

When not using the BCC address, sending works correctly.

The only change in the code (that produces the error) is this:

Report.EmailSettings.BlindCarbonCopy.Text := 'test@somewhere.com';
