Hi,

well, I've checked better this phenomena, and I found out that there's a
repeating issue. This is a standard NOTICE message:

To save privacy, I put KNOWN_USER@CORRECT_DOMAIN as a valid email address,
and UNKNOWN_USER@CORRECT_DOMAIN as a non-existent email address, even if
the domain is correct and is equal in both addresses.

I hope that this can help finding a good solution, I'm really getting
annoyed about them :(

P.S.: I use MySQL for mail delivery instructions.

Thx a lot in advance,
Tony.

Can you post one such message?  Is the domain in the notices a "local"
or a "hosteddomain"?
 
Courier, in it's default configuration, isn't subject to the type of
problem that you describe.  You may have improperly defined a domain
alias, or you've created a ".courier-default" file in
etc/courier/aliasdir, or perhaps you have a backup MX that doesn't
verify users.  The solution would be to remove whatever you've done that
made courier accept messages for user that don't exist.
