I think this comes down to a "do what you have to do" and, if the customer isn't happy, it's on them. It's getting totally out of hand that people are robbing others mail just to try to steal a few dollars or get account numbers. In a similar vein, the wife and I don't mail anything from our mailbox, ESPECIALLY IF IT HAS A CHECK IN IT!!!!!!!!!!!!!!!!!!!! We always take our mail to the post office and drop it in the inside outgoing mail box through the lobby wall. To date, we've not had an issue in doing so but, at the same time, pretty much all we mail out is going to our monthly bills. Just a thought, have you considered getting a PO box? Since you are now taking your shipments inside anyway, it might be a safer way to go.
