civicrm_mailing_bounce_pattern rules for postfix

The standard bounce patterns don't recognise common error messages generated by postfix MTA software. These additions to the civicrm_mailing_bounce_pattern will help:

INSERT INTO `civicrm_mailing_bounce_pattern` VALUES
(125,3,'Host or domain name not found'),
(126,9,'No route to host'),
(127,9,'Network is unreachable'),
(128,4,'lost connection'),
(129,4,'conversation with [^ ]* timed out while');
