Hard links created in /.MobileBackups cause procmail to rename mailbox as bogus

Summary: The new mobile backup feature in Lion creates hard links in /.MobileBackups to files on the parent volume.  procmail thinks that a /var/mail folder with more than one hard link is bogus, and will rename it, emitting the following message:

Renaming bogus mailbox "/var/mail/XXX" info "/var/mail/BOGUS.XXX.NG9lB"

Steps to Reproduce:

* Enable Time Machine
* Make a mobile backup using "tmutil snapshot"
* Run procmail with an empty config and no input: "procmail /dev/null < /dev/null"

Expected Results:

* The user mailbox, /var/mail/USERNAME, is left alone

Actual Results:

* procmail prints the bogus mailbox message, and the user mailbox, /var/mail/USERNAME, is renamed 

Regression:

Notes:

* I validated that the issue was caused by /.MobileBackups by running:

sudo find -samefile /var/mail/USERNAME /.MobileBackups

* It should be possible to patch procmail such that it no longer thinks a multiply-hardlinked /var/mail/USERNAME is bogus.
