The limit is set at twenty. + +JH/05 Bug 2273: Cutthrough delivery left a window where the received messsage + files in the spool were present and unlocked. A queue-runner could spot + them, resulting in a duplicate delivery. Fix that by doing the unlock + after the unlink. Investigation by Tim Stewart. + +JH/06 Bug 2275: The MIME ACL unlocked the received message files early, and + a queue-runner could start a delivery while other operations were ongoing. + Cutthrough delivery was a common victim, resulting in duplicate delivery. + Found and investigated by Tim Stewart. Fix by using the open message data + file handle rather than opening another, and not locally closing it (which + releases a lock) for that case, while creating the temporary .eml format + file for the MIME ACL. Also applies to "regex" and "spam" ACL conditions. + +JH/08 When generating a selfsigned cert, use serial number 1 since zero is not + legitimate. + +JH/09 Bug 2274: Fix logging of cmdline args when starting in an unlinked cwd. + Previously this would segfault. + +JH/10 Fix ARC signing for case when DKIM signing failed. Previously this would + segfault. + +JH/14 Bug 2284: Fix DKIM signing for body lines starting with a pair of dots. + +JH/16 Fix ARC verification to do AS checks in reverse order. + + +Exim version 4.91 +----------------- GF/01 DEFER rather than ERROR on redis cluster MOVED response. - When redis_servers is set to a list of > 1 element, and the Redis servers - in that list are in cluster configuration, convert the REDIS_REPLY_ERROR - case of MOVED into a DEFER case instead, thus moving the query onto the - next server in the list.
