   PH/28 Fixed bug in backwards-compatibility feature of PH/09 (thanks to John
         Jetmore). It would have mis-read ACL variables from pre-4.61 spool files.
  +
  +PH/29 After an address error (typically a 4xx response from a server), Exim
  +      always tries the failing address if it appears in a new message, but
  +      respects the retry time otherwise. This was implemented by checking for
  +      being in a queue run, which isn't quite right. Now it checks the
  +      "first_delivery" flag instead.
  +
  +PH/30 Exim was sometimes attempting to deliver messages that had suffered
  +      address errors (4xx response to RCPT) over the same connection as other
  +      messages routed to the same hosts. Such deliveries are always "forced",
  +      so retry times are not inspected. This resulted in far too many retries
  +      for the affected addresses. The effect occurred only when there were more
  +      hosts than the hosts_max_try setting in the smtp transport when it had
  +      the 4xx errors. Those hosts that it had tried were not added to the list
  +      of hosts for which the message was waiting, so if all were tried, there
  +      was no problem. Two fixes have been applied:
  +
  +      (i)  If there are any address or message errors in an SMTP delivery, none
  +           of the hosts (tried or untried) are now added to the list of hosts
  +           for which the message is waiting, so the message should not be a
  +           candidate for sending over the same connection that was used for a
  +           successful delivery of some other message. This seems entirely
  +           reasonable: after all the message is NOT "waiting for some host".
  +           This is so "obvious" that I'm not sure why it wasn't done
  +           previously. Hope I haven't missed anything, but it can't do any
  +           harm, as the worst effect is to miss an optimization.
  +
  +      (ii) If, despite (i), such a delivery is accidentally attempted, the
  +           routing retry time is respected, so at least it doesn't keep
  +           hammering the server.
