You might try something like this, assuming that you only store mail files under /mnt/backup and only procmail requires access: semanage fcontext -a -t mail_spool_t "/mnt/backup(/.*)?" restorecon -v -R /mnt/backup If you need other things to be able to access it, then we'll have to know more to decide how to label it, or you could possibly move it to a subdir of /mnt/backup like /mnt/backup/spool that can be devoted to procmail's use. > I am reasonably familiar with Linux generally, but am a complete SELinux > virgin (and frankly scared silly of it).
