We use courier maildrop to do the maildir delivery. You configure
"courier-authlib" properly so that it gets its maildir and quota
information for a virtual user from one of LDAP, or MySQL, etc. The
maildrop process simply talks to the courier-authlib process to get
that info. When it then attempts to deliver, it creates/adjusts a
maildirsize file with the quota setting and current mailbox size,
refusing to deliver if the maildir is over its assigned quota.
Integration with Exim is pretty easy. I use it on an older sendmail
system, and am refining it with a development box of Exim.
