Base HP-UX Internet Services (new at 11i original release)

• Support for new mailer and map class:
Mailer: discard
A special internal delivery agent named ‘discard’ is now defined for
use with check_* rulesets and header checking rulesets.
Map class: regex
Sendmail-8.9.3 supports regular expressions using the new map
class ‘regex’. The reqex map can be used to see if an address
matches a certain regular expression. By using such a map in a
check_* ruleset, you can block a certain range of addresses that
would otherwise be considered valid.
• Anti-spam configuration control. To enable some of the new anti-spamming rulesets,
a shell script gen_cf is provided in the /usr/newconfig/etc/mail/cf/cf
directory.
• New header checks. New syntax to do limited checking of header syntax is available.
Documentation
Refer to the Installing and Administering Internet Services manual available on the

BIND 8.1.2
A new version of BIND, BIND 8.1.2, is shipped with HP-UX 11i. This version supports
Dynamic updates via the Dynamic Domain Name Server (DDNS).
NOTE The Dynamic updates, however, are NOT secure, and you are advised to put security
mechanisms in place before using this feature.
The following lists the new features:
• DDNS Change Notification (RFC 1996)
• Completely new configuration syntax
• Flexible, categorized logging system
• IP-address-based access control for queries, zone transfers, and updates that may be
specified on a zone-by-zone basis
• More efficient zone transfers
• Improved performance for servers with thousands of zones
• The server no longer forks for outbound zone transfers
• Many bug fixes
New Configuration File
A BIND configuration file is now named.conf, with many more configurable variables
than in previous releases of BIND. The configuration file in previous versions of BIND was
named.boot.
There are now entirely new areas of configuration, such as, access control lists and
categorized logging. Many options that previously applied to all zones can now be used
selectively.
