mailx and selinux not co-operating

Finally i switched on the enforcing mode on my linux system

Pretty much everything is working except

```

$ echo hello | mail -s test XXXX@YYY.XYZ
2023-08-20 14:39:30 1qXieQ-000Bpa-1P 1qXieQ-000Bpa-1P no recipients 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)

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

```

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

I cant fine any booleans either ..

Please could someone tell me how to get this to work ? has anyone got mailx working with selinux on their system ?
