Synopsis
Trusted
users are those who can run sendmail with the
-f
command-line switch to specify who sent the
message, without generating a warning. Prior to V8.6
sendmail, such users had to be listed with the
T
command (Section 10.8.1.1). That
command was ignored in V8.1 through V8.6, and with those versions
anyone could use the -f
switch. Beginning with
V8.7 sendmail, the T
command
was reintroduced, but it now causes the list of trusted users to be
added to the class $=t
. Now, any user who uses the
-f
switch and who is not listed in class
$=t
will cause the following error message (X-Authentication-Warning:) to be included in the outgoing mail message
(if the PrivacyOptions
option, PrivacyOptions, has authwarnings
set):
X-Authentication-Warning: user set sender to other using -f
See the use_ct_file
feature (FEATURE(use_ct_file)) for an easy way to add users to this class
using the m4 technique.
