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.] + +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. + +PH/31 Installed Andrew Findlay's patch to close the writing end of the socket + in ${readsocket because some servers need this prod. + +PH/32 Added some extra debug output when updating a wait-xxx database. + +PH/33 The hint "could be header name not terminated by colon", which has been + given for certain expansion errors for a long time, was not being given + for the ${if def:h_colon_omitted{... case. + +PH/34 The spec says: "With one important exception, whenever a domain list is + being scanned, $domain contains the subject domain." There was at least + one case where this was not true. + +PH/35 The error "getsockname() failed: connection reset by peer" was being + written to the panic log as well as the main log, but it isn't really + panic-worthy as it just means the connection died rather early on. I have + removed the panic log writing for the ECONNRESET error when getsockname() + fails. + +PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue + runs only) independently of the message's sender address. This meant + that, if the 4xx error was in fact related to the sender, a different + message to the same recipient with a different sender could confuse + things. In particualar, this can happen when sending to a greylisting + server, but other circumstances could also provoke similar problems. + I have changed the default so that the retry time for these errors is now + based a combination of the sender and recipient addresses. This change + can be overridden by setting address_retry_include_sender=false in the + smtp transport. + +PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the + remote server are returned as part of bounce messages.
