Minor wording change to the doc/README.SIEVE file. @@ -62,6 +61,135 @@ Exim version 4.44 16. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0 was its contents. (It was OK if the option was not defined at all.) +17. A "Completed" log line is now written for messages that are removed from + the spool by the -Mrm option. + +18. New variables $sender_verify_failure and $recipient_verify_failure contain + information about exactly what failed. + +19. Added -dd to debug only the daemon process. + +20. Incorporated Michael Haardt's patch to ldap.c for improving the way it + handles timeouts, both on the server side and network timeouts. Renamed the + CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility). + +21. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp". + It is now set to "smtps". + +22. $host_address is now set to the target address during the checking of + ignore_target_hosts. + +23. When checking ignore_target_hosts for an ipliteral router, no host name was + being passed; this would have caused $sender_host_name to have been used if + matching the list had actually called for a host name (not very likely, + since this list is usually IP addresses). A host name is now passed as + "[x.x.x.x]". + +24. Changed the calls that set up the SIGCHLD handler in the daemon to use the + code that specifies a non-restarting handler (typically sigaction() in + modern systems) in an attempt to fix a rare and obscure crash bug. + +25. Narrowed the window for a race in the daemon that could cause it to ignore + SIGCHLD signals. This is not a major problem, because they are used only to + wake it up if nothing else does. + +26. A malformed maildirsize file could cause Exim to calculate negative values + for the mailbox size or file count. Odd effects could occur as a result. + The maildirsize information is now recalculated if the size or filecount + end up negative. + +27. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this + support for a long time. Removed HAVE_SYS_VFS_H. + +28. Installed the latest version of exipick from John Jetmore. + +29. In an address list, if the pattern was not a regular expression, an empty + subject address (from a bounce message) matched only if the pattern was an + empty string. Non-empty patterns were not even tested. This was the wrong + because it is perfectly reasonable to use an empty address as part of a + database query. An empty address is now tested by patterns that are + lookups. However, all the other forms of pattern expect the subject to + contain a local part and a domain, and therefore, for them, an empty + address still always fails if the pattern is not itself empty. + +30. Exim went into a mad DNS loop when attempting to do a callout where the + host was specified on an smtp transport, and looking it up yielded more + than one IP address. + +31. Re-factored the code for checking spool and log partition space into a + function that finds that data and another that does the check. The former + is then used to implement four new variables: $spool_space, $log_space, + $spool_inodes, and $log_inodes. + +32. The RFC2047 encoding function was originally intended for short strings + such as real names; it was not keeping to the 75-character limit for + encoded words that the RFC imposes. It now respects the limit, and + generates multiple encoded words if necessary. To be on the safe side, I + have increased the buffer size for the ${rfc2047: expansion operator from + 1024 to 2048 bytes. + +33. It is now permitted to omit both strings after an "if" condition; if the + condition is true, the result is "true". As before, when the second string + is omitted, a false condition yields an empty string. This makes it less + cumbersome to write custom ACL and router conditions. + +34. Failure to deliver a bounce message always caused it to be frozen, even if + there was an errors_to setting on the router. The errors_to setting is now + respected. + +35. If an IPv6 address is given for -bh or -bhc, it is now converted to the + canonical form (fully expanded) before being placed in + $sender_host_address. + +36. The table in the code that translates DNS record types into text (T_A to + "A" for instance) was missing entries for NS and CNAME. It is just possible + that this could have caused confusion if both these types were looked up + for the same domain, because the text type is used as part of Exim's + per-process caching. But the chance of anyone hitting this buglet seems + very small. + +37. The dnsdb lookup has been extended in a number of ways. + + (1) There is a new type, "zns", which walks up the domain tree until it + finds some nameserver records. It should be used with care. + + (2) There is a new type, "mxh", which is like "mx" except that it returns + just the host names, not the priorities. + + (3) It is now possible to give a list of domains (or IP addresses) to be + looked up. + + (4) It is now possible to specify the separator character for use when + multiple records are returned. + +38. The dnslists ACL condition has been extended: it is now possible to supply + a list of IP addresses and/or domains to be looked up in a particular DNS + domain. + +39. Added log_selector=+queue_time_overall. + +40. When running the queue in the test harness, wait just a tad after forking a + delivery process, to get repeatability of debugging output. + +41. Include certificate and key file names in error message when GnuTLS fails + to set them up, because the GnuTLS error message doesn't include the name + of the failing file when there is a problem reading it. + +42. Allow both -bf and -bF in the same test run. + +43. Did the same fix as 41 above for OpenSSL, which had the same infelicity. + +44. The "Exiscan patch" is now merged into the mainline Exim source. + +45. Sometimes the final signoff response after QUIT could fail to get + transmitted in the non-TLS case. Testing !tls_active instead of tls_active + < 0 before doing a fflush(). This bug looks as though it goes back to the + introduction of TLS in release 3.20, but "sometimes" must have been rare + because the tests only now provoked it. + +46. Reset the locale to "C" after calling embedded Perl, in case it was changed + (this can affect the format of dates). + Exim version 4.43 -----------------
