Sendmail 8.13.3
New Features in Sendmail 8.13.3
Chapter 3120
The enhancement consists of additional arguments, that is, one or more
literal addresses you expect returned when an address must be rejected.
Compared to the dnsbl option, you can specify additional arguments
(upto 5) to specify the return values from lookups. Sendmail ignores
temporary lookup failures in the absence of a third argument, which
must be either t or a full error message. By default, any successful
lookup generates an error. Otherwise, the result of the lookup is
compared with the supplied arguments, and only if a match occurs an
error is generated.
Queuing
Starting with Sendmail 8.13.3, you can define queues according to
selected criteria and process each group with custom settings. The rule
sets then select the queue group to which the message of a recipient
must belong.
You can use the -q command-line option to specify which queue to
display. This is an option available in earlier versions of Sendmail.
Sendmail 8.13.3 has a few additional queue-related options, such as
processing only the quarantined items.
The Default Queue Group
Sendmail 8.13.3 offers a method to define multiple queue directories and
a method to group them by function or specialty. For compatibility with
older versions of Sendmail, there is a special queue group called mqueue.
This is the default queue group. It takes on all the properties of every -q
command, and every queue option.
When you declare additional queue groups, they take all their properties
from the default group, unless you override a particular property with a
specific equate. Table 3-3 describes the equates and the command-line
arguments or options they override.
