[cobalt-users] Need a user-unknown message.

["Dylan O'Donnell" <dylan@xxxxxxxxxxxxxx>]

Cobalt released a patch to avoid the situation where one user recieved
another users email.. this confusion occurred when there was a user called
'sales' and aliases for other accounts as 'sales' (as an example)

After the patch this was resolved and I have not heard from users about
other emails coming through. However, if a user sends mail to -

bob@xxxxxxxxxxxxxx  (which doesnt exist)

and it ends up at
bob@xxxxxxxxxxxxxx  (which does exist)

The only way around it is to give username@xxxxxxxxxxxxxx the alias 'bob'...
otherwise bob@xxxxxxxxxxxxxx will get their mail ...

 the fact remains that the sender was trying to send to domainB.com.au and
not domain A.com.au and should recieve a message saying 'User unknown'
rather than picking another domain with that username and putting it there.


What do you think? Is this a real bug or just bad design?
