Probably not.  I wanted to use IMAPdir for ages but never could.  The biggest 
problem is vpopmail, but everything else that touches the maildirs (i.e. 
maintenance scripts, other mail servers, etc.) will need to be reviewed.

Blech to both ;-)

I think quota (and consequentially blocking users' mail) is pure evil.  I 
think a better approach is to monitor maildir sizes and warn the user as 
appropriate instead.  In case you disagree, there's still issues that make 
maildir-based quotas difficult.  It's fast to check the size of an mbox file, 
and some might find it fast to check the size of a maildir too, but some 
filesystems make checking the size of a maildir very slow.  Technical 
limitations aside, there's no one standard way of implementing quotas in 
maildir AFAIK.  So you have to ensure that everything that has write access 
to the maildir (pop3 server, imap server, spam/old mail deletion scripts, 
smtp server, virtual domain management system) supports quota and works in a 
consistant manner with the others.  I find this to be the wrong approach for 
quota-ing anyways, as the quota checking should exist at a lower level than 
any of the above...

Okay, I'll admit, I thought "shared IMAP folders" sounded really neat when I 
first heard the idea.  Since then though, I've thought more on it, and wonder 
why.  They seem unnecessary (you can just use a shared IMAP *account*, in 
addition to the primary user account and any other accounts in every user's 
MUA).  I would still like to see this feature someday and play with it, but 
at any rate, it doesn't exist in binc now.
