/var/mail is real instead of symlink :: /var/spool/mail is symlink instead of real

First of all, this isnt really a postfix bug, but as the Ubuntu Bugtracking system is quite horrible, i was forced to choose a package.

If you look at /var/mail in Ubuntu, it is a real directoy.

If we look at FHS:

---8<---
/var/mail : User mailbox files (optional)
Purpose

The mail spool must be accessible through /var/mail and the mail spool files must take the form <username>. Note that /var/mail may be a symbolic link to another directory.

User mailbox files in this location must be stored in the standard UNIX mailbox format.

The logical location for this directory was changed from /var/spool/mail in order to bring FHS in-line with nearly every UNIX implementation.
---8<---

So this directory exists for staying incompatible with other UNIX Distributions and mostly is a symlink to /var/spool/mail as it contains parts of the mail spool.

So /var/spool/mail is the "real" directory und /var/mail was created (as optional) as an compatibility directory.

On Ubuntu (and seems like on Debian too), its the other way.

/var/spool/mail is just a fake symlink to /var/mail.

The /var/spool/mail should not be a symlink to an optional directory! Spool-Files belong to /var/spool, not /var/mail and /var/spool/mail just getting a symlink to that is just wrong.

/var/mail is the optional directory which exists for compatibility reason and mostly is just a symlink
/var/spool/mail is the real thing!

---8<---
user@host:~$ file /var/spool/mail
/var/spool/mail: symbolic link to `../mail'
---8<---

thats just wrong!
