[Dovecot] few questions about 1.1*

[Daniel]

Hi!

I'm testing 1.1, and have some questions.
(How) Can I override the default maildir++ quota setting (I mean 
quota_rule) in the userdb, so that one won't have quota at all. Right 
now I'm setting a very high limit in the userdb with 
quota_rule=*:storage=99G in the extra field.

Prior to 1.1 I was using 1.0 and had fs quota. I've had set up dovecot 
so that the indexes were stored on another partition where there were 
no fs quotas for the users. Now I'm trying to use maildir++ quota, and 
wondering if there is still any use of keeping the index files on a 
separate partition.

This will be maybe a bit stupid, but do I still need the quota plugin to 
be loaded in the protocol {imap,pop3,lda} sections if I'm using the 
above mentioned new 1.1 maildir++ quota?
Furthermore, will deliver be aware of the new quota system?

Thanks!

Daniel
