each email address is still displayed in the receiving inbox
i have this in the form:
<label>Select up to 3 recipients</label>
[select* your-recipient multiple
"Email one|one@test.com"
"Email two|two@test.com"
"Email three|three@test.com"
"Email four|four@test.com"]
then within additional headers I have:
Bcc:one@test.com
Bcc:two@test.com
Bcc:three@test.com
Bcc:four@test.com
The email arrives in the recipient inbox and the selection of email addresses made from the dropdown are always displayed
