I'm running Debian/Postfix/mySQL mapping virtual mailboxes and quota, but when I increase the quota field in mysql for the user to 10G, postfix somehow doesn't see it and gives my webmail client, Roundcube, a 100% of allowed space warning still. There's no max space limitation on Roundcube, they say it's relative to maildir size. I was able to successfully increase the maildir size a few months ago from 100M to 1G. My hdd is 13% full.
I think I found in the roundcube logs that courier-imap is telling roundcube what the quota is, that I guess it pulls from the mysql db, is there any other place in postfix that it could be set besides mysql-courier-imap?
