Courier Imap and Quotas?

[Justin Bennett]

I'm playing with Courier Imap as some of you know, I'm going to deploy 
it in the next few months, I'm running sendmail/procmail with courier. I 
noticed my wife had a message when checking her UB mail, that she was 
90% of quota. Is this setup on the courier imap side or is this a MDA 
thing? Basically could I set this up with my setup? If not no biggie.
