key / crt permissions constantly

I don't really get why I am confronted with sendmail thinking it knows better how I should put permissions on my key and crt files.
Why do I even get this error, while the permissions are just fine
file /home/acme/test.cer unsafe: Permission denied
-rw-r-----+  1 acme acme 1972 Jul 29 00:10 test.cer
and
-rw-r--r--+  1 acme acme 1972 Jul 29 00:10 test.cer
and
-rw-r--r--+  1 acme root 1972 Jul 29 00:10 test.cer
Besides that, who cares about certs, these are even distributed unsecurly.
How can I turn of any permissions checks on key/crt files
(I already have this
define(`confDONT_BLAME_SENDMAIL', `groupreadablekeyfile')dnl )
