Hallo.

We use dovecot 1.2.12 running under Solaris 9 and wanted to set up a second filesystem quota root because the mail folders are in the users home directories and the inboxes of all users are in /var/mail. This is defined in dovecot.conf:

quota = fs:Home-Verzeichnis:noenforcing quota2 = fs:INBOX:noenforcing:mount=/var/mail

This second quota did not work, but now I found the reason why. The mountpoint_get in src/lib/mountpoint.c needs to call resetmnttab to find the filesystem for the second quota root (see man resetmnttab). The following patches correct this and also adds some debugging code to src/plugins/quota/quota-fs.c to show the processing of quota2. These patches are only needed for Solaris with filesystem quotas.
