**************************************************************************************************
|
||||
ATTENTION: requirements changed - as dns queries are now performed asynchronously, postfwd from
|
||||
v1.10pre2 and above needs the perl module Net::DNS::Async! it is available via CPAN
|
||||
and installed for my tests without any problems on different linux and solaris systems
|
||||
ATTENTION: requirements changed - postfwd since v1.10pre8 now uses Net::DNS.
|
||||
Net::DNS::Async and Net::CIDR::Lite are not required anymore.
|
||||
NOTE: please see the docs ('postfwd -m' or 'perldoc postfwd') for more information
|
||||
**************************************************************************************************

|
||||
1.10pre8b
|
||||
==========
|
||||
- bugfix: fixed two warnings about logging of undefined values in verbose mode
|
||||
|
||||
1.10pre8a
|
||||
==========
|
||||
- bugfix: item plugins have been made available as cache-id items. this fixes a minor issue with
|
||||
--cache-rdomain-only and version 1.10pre8
|
||||
|
||||
1.10pre8
|
||||
=========
|
||||
- code: Net::DNS::Async is no longer used. The parameters --dns_queuesize and
|
||||
--dns_retries are still valid but have no function. The option --dns_timeout
|
||||
now defaults to 14s and applies to all rules containing dns items.
|
||||
- code: Net::CIDR::Lite is not required any longer.
|
||||
- feature: the new variable $$request_hits contains a list of all matching ruleids
|
||||
- feature: the new variable $$dnsbltext allows access to txt records of rbls
|
||||
- feature: new options --no-rulestats and --nodnslog
|
||||
- feature: ttls of the dns responses override --cache-rbl-timeout when bigger, which means
|
||||
that you can set the option to 0 if you want to use the ttl of the dns answer.
|
||||
- feature: new item "rhsbl_helo" allows to check helo against rhsbls
|
||||
- bugfix: disabled fallback to synchronous dns on timed out rbls, default is now
|
||||
to disable non responding dnsbls after 11 timeouts for 1200 seconds.
|
||||
use --dns_timeout_max and --dns_timeout_interval to adjust these settings.
|
||||
- bugfix: days=Wed now means exactly Wednesday. to use a range you may
|
||||
still specify days=Wed- days=-Wed and days=Tue-Thu
|
||||
this applies to all date and time items
|
||||
- code: --shortlog is now default behaviour (use -v to see more)
|
||||
- code: changed Net::Server behaviour to ignore syslog errors
|
||||
|
||||

||||
