If you're about to set up, don't use such an old version.  There were a LOT of 
fixes between 0.99.11 and 0.99.14 (the latest 0.99 release), many of which are 
quite important.

I have quotas enabled on my system (running 0.99.14... 1.0 is missing _one_ 
feature for me to migrate) and the only problem I see is that users don't get 
new mail delivered when they exceed their quota.

However, other people have noticed that users can not log in, and this is 
because Dovecot can't modify/extend its control files due to quota limits.  As 
was just this week pointed out on the mailing list, you can add a CONTROL path 
to the mail env to specify where Dovecot is to create these files, thus avoiding 
the issue.

 From what I recall, aside from the actual mail folder, you can additionally 
specify:
INBOX= where to find the inbox (not sure if this is in 0.99)
INDEX= where to create the indexes
CONTROL= where to create other Dovecot control files

Check out http://wiki.dovecot.org/moin.cgi/MailLocation for some more details, 
or search this mailing list.
