It's usual for such mails to be sent to the sender, so they know that the 
address is bad, and can take alternative action. Are you catering for users 
who wouldn't understand what was going on in this case?

The only thing I could suggest here is: either set Reply-To:, which may 
work but will probably annoy users, or use an exim rewrite rule to change 
the smtp from address (E-flag?) to the return address on all outgoing 
mails. However, this may have undesirable effects on on other mail systems, 
especially in the security and message logging/reporting area (because if 
you do this, all mail from your domain will appear to be from one address).

Could you instead set up a filter for inbound messages that checks for 
returned mail errors addressed to your users and diverts them to the 
required place, or even better mangles them to an intelligible form?
