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 a :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 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
