I've set the system to not use automount, rebooted it, and run those commands 
again.

In the case of x-automount absolutely.  In the case of not using automount, 
how else would it be happening?

# ls -ldZ /mail
drwxr-xr-x. 1 vmail vmail system_u:object_r:nfsd_rw_t:s0 754 May 10 12:41 
/mail
# umount /mail ; mount /mail
# ls -ldZ /mail
drwxr-xr-x. 1 vmail vmail system_u:object_r:mail_spool_t:s0 754 May 10 12:41 
/mail

Yes, it works fine.

I've also attached the latest version of /etc/fstab.
