[Plugin: Fast and Secure Contact Form] Mail to fields

I have seen that this is used to make multiple to: field
contact1, [email protected]
contact2, [email protected]

Is there a way to add two addresses to each? I tried using a comma and another email, but it only goes to one address. I know you can bcc every entry but I don’t want to do that.

contact1, [email protected], [email protected] (didn’t work)
contact2, [email protected]

Thanks!
