  25 were already included with Postfix versions 2.6 and 2.7.

  28 <h3> Fixed with Postfix 2.5.7 </h3>
  29
  30 <ul>
  31
  32 <li>
  33 <p>
  34   (low) The installation/upgrade procedure did not automatically
  35   create the <a href="../postconf.5.html#data_directory">data_directory</a>.
  36 </p>
  37
  38 <li> <p>
  39   (medium) In the "new queue manager", the _destination_rate_delay
  40   code needed to postpone the job scheduler updates after delivery
  41   completion, otherwise the scheduler could loop on blocked jobs.
  42 </p>
  43
  44 <li> <p>
  45   (low) The queue manager used <i>transport</i>_concurrency_failed_cohort_limit
  46   instead of <a href="../postconf.5.html#transport_destination_concurrency_failed_cohort_limit"><i>transport</i>_destination_concurrency_failed_cohort_limit</a>
  47   as documented.
  48 </p>
  49
  50 <li> <p>
  51   (low) The SMTP client disabled MIME parsing despite non-empty
  52   settings for <a href="../postconf.5.html#smtp_header_checks">smtp_header_checks</a>, <a href="../postconf.5.html#smtp_mime_header_checks">smtp_mime_header_checks</a>,
  53   <a href="../postconf.5.html#smtp_nested_header_checks">smtp_nested_header_checks</a>, or <a href="../postconf.5.html#smtp_body_checks">smtp_body_checks</a>.
  54 </p>
  55
  56 </ul>

  58 <h3> Fixed with Postfix 2.5.7, 2.4.11, 2.3.17 </h3>
  59
  60 <ul>
  61
  62 <li> <p>
  63   (medium) The postsuper command re-enabled the SIGHUP signal when
  64   it was set to "ignore". This could result in random "Postfix
  65   integrity check failed" errors at boot time (POSIX SIGHUP death),
  66   causing Postfix not to start automatically.
