Sendmail 8.13.3 release notes for HP-UX 11i v1, HP-UX 11i v2 and HP-UX 11i v3

— The SIGHUP signal now restarts a Sendmail process that runs the queue at an
interval of 15 minutes.
— The NiceQueueRun option sets the priority of queue runners.
— The -qf and -v option run the Sendmail queue in the foreground. Normally,
Sendmail runs the queue in the background when Sendmail is invoked with
the -q option.
Sendmail runs the queue in the background when Sendmail is invoked with
-q option. However, if you use the new -qf option or -v option, Sendmail
runs the queue in the foreground.
— The value QueueSortOrder=Random sorts the queue randomly. This feature
is useful when several queue runners are started manually to avoid contention.
— The value QueueSortOrder=Modification sorts the queue based on the
time when the qf file was modified.
• Support for DeliverBy SMTP extension (RFC 2852):
— Support for RFC 2852 (Deliver by SMTP Service Extension), that allows a client
to specify an amount of time within which an email must be delivered. A new
option DeliveryByMin is added to set the minimum amount of time or to
disable the extension.
• MX records are looked up for the FallBackMXhost. To revert to the previous
behavior where no MX record are referred, enclose the host name in square brackets
(‘[’ and ‘]’).
• The DelayLA option delays connections if the load average exceeds the specified
value. The default value for DelayLA is zero. A value greater than zero causes
Sendmail 8.13.3 to sleep for one second on most SMTP commands and before
accepting connections, if the load average is exceeded.
Sendmail 8.13.3 includes the following additional new options:
• LDAP map options:
— The -w option allows you to specify the LDAP API or protocol version.
— The -H option allows you to specify an LDAP URL instead of specifying the
LDAP server using a -h host and -p port. With the -H option, you can use
LDAP over SSL and connections through named sockets if your LDAP library
supports it the security feature.
• The MailboxDatabase option specifies the type of mailbox database used to
look up local mail recipients; the default value for this option is pw, which indicates
that getpwnam() is used. You can use the new mailbox database types to add
custom code to libsm or mbdb.c.
• If the new option FastSplit has a value greater than zero, it suppresses the MX
lookups on addresses when they are initially sorted. This may result in faster
envelope splitting. If the mail is submitted directly from the command line, the
