[Dovecot] 1.0.rc12 released

http://dovecot.org/releases/dovecot-1.0.rc12.tar.gz http://dovecot.org/releases/dovecot-1.0.rc12.tar.gz.sig

Since rc11 has problems compiling with BSDs, here's a new release. Just two changes:

- rc11 didn't compile with some compilers
- default_mail_env fallbacking was broken with --exec-mail

Here's also again the rc11 changes:

* Renamed default_mail_env to mail_location. default_mail_env still
  works for backwards compatibility.
* deliver: When sending rejects, don't include Content-Type in the
  rejected mail's headers.
* LDAP changes:
        * If auth binds are used, bind back to the default dn before doing
      a search. Otherwise it could fail if a user gave an invalid
      password.
    * Initial binding at connect is now done asynchronously.
    * Use pass_attrs even with auth_bind=yes since it may contain
      useful non-password fields.

+ passdb checkpassword: Give TCPLOCALIP and TCPREMOTEIP and PROTO=TCP
  environments to the checkpassword binary so we're UCSPI (and vchkpw)
  compatible.
- mbox handling was a bit broken in rc10
- Using Dovecot via inetd kept crashing dovecot master
- deliver: Don't crash with -f "". Changed the default from envelope
  to be "MAILER-DAEMON".
- INBOX wasn't shown with LSUB command if only prefixed namespaces
  were used.
- passdb ldap: Reconnecting to LDAP server wasn't working with
  auth binds.
- passdb sql: Non-plaintext authentication didn't work
- MySQL passdb ignored all non-password checks, such as allow_nets
- trash plugin was broken
