Is it possible to have Postfix issue a warning when the "mailbox_size_limit" is about to be reached? Perhaps emailing the user once per day, that they are almost out of space?
I am using Ubuntu 8.10, Postfix 2.5.5, Dovecot 1.1.4, Squirrelmail 1.4.15, with Maildir directories. There is a Squirrelmail quota plugin, but it does not seem to support the Postfix limit. Ideally the user would get an email once per day that they were within 80% of their limit. Or is something like this normally done from within a shell script?
