Description Anthony Messina 2018-11-24 16:23:48 UTC 
AVC avc:  denied  { map } for  pid=690 comm="saslauthd" path="/run/saslauthd/cache.mmap" dev="tmpfs" ino=27073 scontext=system_u:system_r:saslauthd_t:s0 tcontext=system_u:object_r:saslauthd_var_run_t:s0 tclass=file permissive=1

audit2allow reports:
#!!!! This avc can be allowed using the boolean 'domain_can_mmap_files'
allow saslauthd_t saslauthd_var_run_t:file map;

It would be preferable to 
allow saslauthd_t saslauthd_var_run_t:file map;
in the upstream policy rather than enable domain_can_mmap_files for everything
