So it looks like Drupal runs postfix to send the mail, as user 161044. 
Postfix probably accepts the mail locally so you get no error message. 
When the receiving MTA bounces the message you don't get that either.

So that's not very relevant.  When you're talking about a user sending 
mail, "incoming" mail is only relevant if it means mail delivered to 
that user (which is where bounces ought to go and those are what tell 
you what the problem is).  Mail coming in to your domain is probably 
handled by a completely separate system.

More later.
