Since we upgraded last year to Solaris 10 with zfs filesystems on our Sparc server still using a similar setup with separate filesystems for home directories and inboxes we have no working quota plugin anymore. Currently we use dovecot 2.0.13.

Are there any plans or whishes to get the filesystem quota code working again under zfs and Solaris?

How are you setting up the zfs quotas? The original zfs implementation didn't have user quotas. You could only add quotas to individual file systems as a whole. They apparently added it into the source base in 2009: http://blogs.oracle.com/chrisg/entry/user_and_group_quotas_for but I'm not sure when/if it made it to production. My sol10u8 * (10/09) has it in the man page, but I know some things in the man page isn't in s10 (like sharesmb), so, as they say, ymmv.

The current doc for user quotas are here: http://download.oracle.com/docs/cd/E19253-01/819-5461/gazud/index.html

If you don't want to use the filesystem quotas, you have to change your rules/configuration to match what dovecot has. See doc/wiki/Quota.Configuration.txt. Hope this helps.
