I'm running Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAssassin, ClamAV) and wondering how to increase the quotas. The system is up and running, and was configured with the tutorial defaults (10MB). The problem I have is showing up often on my personal email on one of those domains. Even though I have used phpmyadmin and increased the size to 50MB, I will get the quota exceeded message if I try to log in with Squirrelmail (a du shows the /home/vmaildomain/myusername = 13MB), so I assume Squirrelmail must use the 10MB groupquota in it's defaults? What I'd like to know is: A) How can I change the settings over the entire server so I can give them up to 100MB if I want? It's unnecessary to immediately change the users, that can be done one by one as they ask. I just need to clear the immediate problem, and be able to set a bigger quota when I enter or add a user. I'm rarely on the same workstation, so I rely on Squirrelmail.
