I want to set every single account we have to fail rather than use the default username@domain for the catch-all account. The only way I have found to do this is to log in to each account's cpanel and set it manually, 1 by 1. We have a lot of accounts so this would be a very painful process.
I know i can set the default in tweak settings. I have already done this, but the problem is i already have a ton of accounts already created with a catch-all account that nobody checks, causing quotas to fill.
Anyone have any ideas? Where is this setting stored? If i knew which file it was stored in i could possible write a script to go through and update all of the config files associated with this setting.
