  24 Postfix stable release 2.6.1 fixes one defect in Milter support.
  25 This does not affect Postfix versions 2.5 and earlier.
  26 </p>
  27
  28 <ul>
  29
  30 <li> <p>
  31   Queue file corruption under very specific conditions: (<a href="postconf.5.html#smtpd_milters">smtpd_milters</a>
  32   or <a href="postconf.5.html#non_smtpd_milters">non_smtpd_milters</a>) enabled, AND <a href="postconf.5.html#delay_warning_time">delay_warning_time</a> enabled,
  33   AND mail delivery delays, AND short envelope sender addresses
  34   (e.g., sendmail command-line submissions with bare usernames as
  35   the sender, but not bounce messages).
  36 </p>
  37
  38 <p>
  39   The queue file would be corrupted when the <a href="postconf.5.html#delay_warning_time">delay_warning_time</a>
  40   record was marked as "done" after sending the "your mail is
  41   delayed" notice.  The defect was introduced with Postfix 2.3, but
  42   it could not cause corruption before the change dated 20090427.
