If you don't need deliver you could use
http://wiki.dovecot.org/PostLoginScripting

v1.1 makes this a bit easier. There you'll need to use:

  #quota = maildir
  #   quota_rule = *:storage=1048576
  #   quota_rule2 = Trash:storage=102400
  # User has now 1GB quota, but when saving to Trash mailbox the user
gets
  # additional 100MB.

So only the quota_rule needs to be retrieved from userdb.

I've been thinking about changing the storage-format also so that it
could support bytes as well. Suggestions welcome how this could be best
achieved. Maybe so that after the numbers there could be
(case-insensitive) "k" / "kb" for kilobytes, "m" / "mb" for megabytes,
"g" / "gb" for gigabytes, "b" / "s" for bytes. The default would still
stay as kilobytes though.

Also the LDAP queries need to be made more flexible so it would be
possible to do something like:

user_attrs {
  homeDirectory = home
  uidNumber = uid
  gidNumber = gid
  quotaBytes = quota_rule=*:storage=%$b
  maildir = mail=Maildir:%$:INDEX=/var/index/%u
}

So %$ would expand to the field that was retrieved from LDAP and other %
vars could be used too. %$ is a bit ugly though, but I'm not sure what
would be better that isn't already in use (and won't be in future). %1
would be nice, but numbers are already used for other purposes.
