Adds a auth_dovecot to qmail a la auth_imap (courier-imap).

You have to configure auth as follows on dovecot.conf (see a sample here):

  passdb checkpassword {
    # Path for checkpassword binary
    args = /var/qmail/bin/auth_dovecot ./Maildir/
  }

Quota supported via (v1.1 or v1.0 with quota-rewrite patch):

  plugin {
    quota = maildir
    # This one will be your default, auth_dovecot will
    # overwrite it with what it gets from ldap
    quota_rule = *:storage=1GB
  }

or (v1.0):

  plugin {
    quota = maildir:storage=2000000:messages=100000
  }
		    
Remember to have dirmaker configured (as you would for qmail) if *DIRMAKE
is selected:

root@mail:~# cat /var/qmail/control/dirmaker
/var/qmail/bin/dirmaker
root@mail:~# cat /var/qmail/bin/dirmaker
#!/bin/sh
/bin/mkdir -m 700 -p $1
#EOF

QLDAP_CLUSTER is supported throught dovecot's awesome proxy engine since patch v0.4. Upgrade.

Should be applied to clean qmail-ldap-1.03-20060201.

Patch to alter bigbrother to monitor allowing aditionaly to configure the From
address, Subject and date to expire.

Main advantage is that the original message is sent in a message/rfc822 part
with the envelope as configured thus nulling any possible bounces to the
original sender. Read QLDAPINSTALL for details.

May be of use in ISP scenarios.
