It's just writing an additional bit of text to the maillog, preferably at the same time, in the same line, it writes "sender non-delivery notification" to
You're misinterpreting the logs somewhere. Postfix does not and cannot send non-delivery notifications for mail it doesn't receive.
The sender non-delivery is not related to the other issue of too many recipients.
Also, our customer is unable to determine which, if any, of his emails were actually sent. He just sees the "non-delivery notification" email
Ah, now we learn that you're referring to a client submission rather than general incoming email. All the desktop mail clients I know of will abort the whole transaction if there is an error -- no mail is sent. Is the client using some sort of (garbage) MTA rather than a normal desktop MUA? Did they maybe attempt multiple submissions with a partial recipient list?
