Minor wording change to the doc/README.SIEVE file. @@ -102,6 +101,146 @@ Exim version 4.44 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. The behaviour when one of the lookups defers can be + controlled by a keyword. + + (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). + +47. exim_tidydb, when checking for the continued existence of a message for + which it has found a message-specific retry record, was not finding + messages that were in split spool directories. Consequently, it was + deleting retry records that should have stayed in existence. + +48. Steve fixed some bugs in eximstats. + +49. The SPA authentication driver was not abandoning authentication and moving + on to the next authenticator when an expansion was forced to fail, + contradicting the general specification for all authenticators. Instead it + was generating a temporary error. It now behaves as specified. + +50. The default ordering of permitted cipher suites for GnuTLS was pessimal + (the order specifies the preference for clients). The order is now AES256, + AES128, 3DES, ARCFOUR128. + +51. Small patch to Sieve code - explicitly set From: when generating an + autoreply. + +52. Exim crashed if a remote delivery caused a very long error message to be + recorded - for instance if somebody sent an entire SpamAssassin report back + as a large number of 550 error lines. This bug was coincidentally fixed by + increasing the size of one of Exim's internal buffers (big_buffer) that + happened as part of the Exiscan merge. However, to be on the safe side, I + have made the code more robust (and fixed the comments that describe what + is going on). + +53. Now that there can be additional text after "Completed" in log lines (if + the queue_time_overall log selector is set), a one-byte patch to exigrep + was needed to allow it to recognize "Completed" as not the last thing in + the line. + +54. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A + patch that reportedly fixes this has been added. I am not expert enough to + create a test for it. This is what the patch creator wrote: + + "I found a little strange behaviour of ldap code when working with + Windows 2003 AD Domain, where users was placed in more than one + Organization Units. When I tried to give exim partial DN, the exit code + of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE. + But simultaneously result of request was absolutely normal ldap result, + so I produce this patch..." + +55. Some experimental protocols are using DNS PTR records for new purposes. The + keys for these records are domain names, not reversed IP addresses. The + dnsdb lookup now tests whether it's key is an IP address. If not, it leaves + it alone. Component reversal etc. now happens only for IP addresses. + +56. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP. + Exim version 4.43 -----------------
