SAFENFSPATHCONF If you have verified that a pathconf(2) call with a _PC_CHOWN_RESTRICTED argument
returns a negative or zero value when a check is made on an NFS filesystem, where the
underlying system allows users to give away files to other users, you should define this
compile-time macro.

118 | Chapter 3: Tune sendmail with Compile-Time Macros
Usually, you will not have to define any of these compile-time macros unless you are
porting sendmail to a completely new system.
If you are running a precompiled sendmail, you can use the -d0.10 debugging commandline
switch (?§15.7.3 on page 543) to determine whether any are supported (each is
supported that appears in the list). New ports should be reported to sendmail@sendmail.
org so that they can be folded into future releases.
3.4.18 LA_TYPE
Define your load-average support Port, edit sendmail/conf.h
The load average is the average number of blocked processes (processes that are runnable
but not able to run because of a lack of resources) over the last minute. The sendmail
program can vary its behavior appropriately as the load average changes. Thresholds for
change are defined by the options shown in Table 24-9 in ?§24.7.4.
The method that is used to get the current load average from the operating system varies
widely.
