Exim, imp, www-data question

[Mike Egglestone <megglestone@heritage.sd57.bc.ca>]

Hi all,

I'm running exim on Potato, with IMP,Postgresql and PHP3.

When I setup exim, it asks which account to use to receive system
emails and such.
So, as usual, I put in my account name. 
I have noticed then when other users on the IMP system
send an email with bad syntax, their email gets sent back to 
them basically telling them that they can't spell.
However, I noticed that my account receives the same 
error email that the user received.
The error comes from www-data@localhost I believe.

I would like to know if this is normal?

thanks for your time.

Mike
