Previously, when an argument included a close-brace character (eg. it itself used an expansion) an error occurred. +JH/16 Move running the smtp connect ACL to before, for TLS-on-connect ports, + starting TLS. Previously it was after, meaning that attackers on such + ports had to be screened using the host_reject_connection main config + option. The new sequence aligns better with the STARTTLS behaviour, and + permits defences against crypto-processing load attacks, even though it + is strictly an incompatible change. + Also, avoid sending any SMTP fail response for either the connect ACL + or host_reject_connection, for TLS-on-connect ports. + +JH/17 Permit the ACL "encrypted" condition to be used in a HELO/EHLO ACL, + Previously this was not permitted, but it makes reasonable sense. + While there, restore a restriction on using it from a connect ACL; given + the change JH/16 it could only return false (and before 4.91 was not + permitted). + +JH/18 Fix a fencepost error in logging. Previously (since 4.92) when a log line + was exactly sized compared to the log buffer, a crash occurred with the + misleading message "bad memory reference; pool not found". + Found and traced by Jasen Betts. + Exim version 4.96 -----------------
