found in headers
Can't send mail: sendmail process failed with error code 1
however the same works fine when I put selinux in permissive state (no
warnings shown in audit/dmesg).
This is NOT a configuration issue but looks like selinux compatibility issue
A quick ltrace says
1qXia0-000BPb-0a Failed to create spool file
/var/spool/exim4//input//1qXia0-000BPb-0a-D: Permission denied
However there are no avc: messages for me to allow this through in my
selinux module
I even tried a custom policy
allow unconfined_t exim_spool_t:file { open read write create };
allow unconfined_t exim_spool_t:dir { open read write };
since /var/spool/exim4/input has exim_spool_dir set in it
ls -lZd

I cant fine any booleans either ..
Many scripts including chkrootkit and tripwire are failing because mail
cannot send mails(becauses debian uses bsd-mailx as default)
