Some complicated redirection strategies + went wrong when messages had multiple recipients, and made Exim's + behaviour dependent on the order in which the addresses were given. + + I have moved the duplicate checking until after the routing is complete. + Exim scans the addresses that are assigned to local and remote + transports, and removes any duplicates. This means that more work will be + done, as duplicates will always all be routed, but duplicates are + presumably rare, so I don't expect this is of any significance. + + For deliveries to pipes, files, and autoreplies, the duplicate checking + still happens during the routing process, since they are not going to be + routed further. + +PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner. + It corrects a timeout issue with spamd. This is Ian's comment: "The + background is that sometimes spamd either never reads data from a + connection it has accepted, or it never writes response data. The exiscan + spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it + blindly assumes that writes won't block so it may never time out." + +PH/39 Allow G after quota size as well as K and M. + +PH/40 The value set for $authenticated_id in an authenticator may not contain + binary zeroes or newlines because the value is written to log lines and + to spool files.

There are also a few cases where bland messages such + as "unrouteable address" or "local delivery error" are given. + +PH/43 $value is now also set for the "else" part of a ${run expansion. + +PH/44 Applied patch from the Sieve maintainer: "The vacation draft is still + being worked on, but at least Exim now implements the latest version to + play with." + +PH/45 In a pipe transport, although a timeout while waiting for the pipe + process to complete was treated as a delivery failure, a timeout while + writing the message to the pipe was logged, but erroneously treated as a + successful delivery. Such timeouts include transport filter timeouts. For + consistency with the overall process timeout, these timeouts are now + treated as errors, giving rise to delivery failures by default. However, + there is now a new Boolean option for the pipe transport called + timeout_defer, which, if set TRUE, converts the failures into defers for + both kinds of timeout. A transport filter timeout is now identified in + the log output. + A note about Exim versions 4.44 and 4.50 ----------------------------------------
