-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/29 [Removed. This was a change that I later backed out, and forgot to
+ correct the ChangeLog entry (that I had efficiently created) before
+ committing the later change.]
