Quota issue with parent servers after they've been converted to child servers

Ok, let me see if I can make this clear.

There's an issue in the lookup-domain deamon with parent servers that have been converted to child servers.

This was the previous setup: Server Domain A (quota limit = 1 gb) -> Sub Server Domain B (no quota limit since this is a child and therefor falls within the parent limit)

This setup has been changed to: Server Domain C (quota limit = 2gb) -> Sub Server Domain A -> Sub Server Domain B

Even though domain c (the parent server) has been setup with a limit of 2gb, we were getting quota errors while delivering email to mailboxes in Domain B

We've double checked the debian quota settings and verfied that there was only one group limit (Domain C) and there was no limit enforced on sub user level).

Logging in procmail log:

After manually requesting the quota from the lookup deamon:

This response was unexpected, since there is no limit enforced on the user level, and the domainc account had over 900mb free space.

After looking a bit further, it turned out that there was still a 1gb limit defined in the domainb.com server file (/etc/webmin/virtual-server/domains/132568284011416).

After bumping up that limit to 3gb, mail started to arrive without issues again. It would seem that, webmin does not look at the quota file defined in linux, but rather to the server configuration.
