Name
-d27.4
Synopsis
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 a
:include
: file beyond that printed with
-d27.2
:
include(file) ← printed with -d27.2 ruid=real-user-ideuid=effective-user-id←printed with -d27.4
This shows the real user-id (the
ruid=
) and effective user-id
(the euid=
) of the current running
sendmail.
The -d27.4
debugging switch causes
sendmail to print an error if a
:include
: or ~/.forward file
cannot be opened for reading:
include: open: reason here
