Well, that was easy.

So, it's a permissions problem. The relevant bits:

Code:
Jan 31 15:46:51 25612-21212 dovecot: deliver(cbj4074@xanderit.com): chdir(/var/vmail/xanderit.com/cbj4074) failed: Permission denied
Jan 31 15:46:51 25612-21212 dovecot: deliver(cbj4074@xanderit.com): sieve: stat(/var/vmail/xanderit.com/cbj4074/.sieve) failed: Permission denied (using global script path in stead)
Jan 31 15:46:51 25612-21212 dovecot: deliver(cbj4074@xanderit.com): stat(/var/vmail/xanderit.com/cbj4074/Maildir) failed: Permission denied
Jan 31 15:46:51 25612-21212 dovecot: deliver(cbj4074@xanderit.com): stat(/var/vmail/xanderit.com/cbj4074/Maildir/tmp) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +x perm: /var/vmail/xanderit.com)
Jan 31 15:46:51 25612-21212 dovecot: deliver(cbj4074@xanderit.com): msgid=<20120130015002.0A6FDC7483CC@25612-21212.vps.digitalpacific.com.au>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2012-01-31 15:46:51]

Jan 31 15:48:24 25612-21212 dovecot: dovecot: Fatal: chdir(/var/vmail/xanderit.com/admin/) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +x perm: /var/vmail/xanderit.com)
(Note that the /var/log/auth.log excerpt doesn't contain anything relevant; those root login failures are unrelated and most likely someone is attempting to brute-force his way into your box [which is inevitable]).

Recall that the permissions on /var/vmail were set incorrectly on your system at some point in the past (we covered that in a previous post in this thread). Please look back over that discussion and ensure that the permissions are correct.

Obviously, it these permissions keep being changed "for no reason", we need to isolate the cause.
