The same thing happens both times.
1) mail client sends the email.
2) mail server A accepts the message. The client disconnects.
What happens afterwards isn't detected by the mail clilent.
3) server A passes to mail server B.
...
n) server Y passes to server Z.
n+1) Destination mail server reached.
n+2) Whoops! There's nobody here by that name!
n+3) Send a bounce email to server Y.
n+4) Server Y passes bounce to server X.
...
m) Server B passes bounce to server A.
m+1) Server A receives the bounce.
m+2) Server A receives bounce email, stores it in the users' inbox.
This process can take minutes or days. Something along the chain might decide to wait and retry a couple times.
gmail
does not know you're sending to an invalid email address.
gmail
does not know the email didn't get through.
gmail just receives a bounce message, long after the fact, like everything else.
So there's not really any help for it. That's just the way email works. You need to start pawing through received mail to get bounces, and how to do that depends on 1) whether your server receives email at all, 2) how it does so and what it does with it.
