Hey Davide,

You don't *have* to, but you can. Now whether you should or shouldn't is 
up to you. The downside of enabling this is that if John is over quota, 
then if you try to send a mail to three recipients John, Mary and 
Socrates postfix will refuse to relay mail for any of them, even if only 
John is over quota. This has confused my users who couldn't understand 
why things were like this, but apparently this is how postfix is 
designed to work ? (or is it a protocol limitation ?)

I don't know if other people here can testify of this or have they found 
a way to circumvent this ? (or more likely is it simply a bad 
configuration on my part ^:^' ?)

Yassine.
