-d27.4
Print not safe Debug command-line switch
A ~/.forward file must be owned
by the user or by root. If it
is not, it is considered unsafe, and
sendmail ignores it. The
-d27.4
debugging switch causes
sendmail to print a message
describing any such file it finds unsafe:
include: not safe (uid=user-id)
Note that a file is considered unsafe if, among other things, it lacks all read permissions.
The -d27.4
debugging switch also causes
sendmail to print information
about an :include
: file beyond that printed with
-d27.2
:
include(file) ← printed with -d27.2 ruid=real-user-id euid=effective-user-id ← printed with -d27.4
This shows the real user-id (the
ruid=
) and
effective user-id (the euid=
) of the currently
running sendmail.
The -d27.4
debugging switch causes
sendmail to print an error if
an :include
: or
~/.forward file cannot be
opened for reading:
include: open: reason here
