You should not be attempting to deliver mail to root directly. Instead you should forward root's mail to a real user with /etc/aliases; postfix's local(8) will not allow you to deliver mail as root.

You should have aliased root to a mortal user. Postfix will not invoke a mailbox_command as root. In broader terms, you should only use root for actual system administration, and not for user tasks such as reading and sending mail. See and edit /etc/aliases, then run "newaliases". Example: root: thufir http://www.postfix.org/postconf.5.html#default_privs http://www.postfix.org/postconf.5.html#mailbox_command http://www.postfix.org/local.8.html http://www.postfix.org/aliases.5.html After you have done this, requeue the message: # postsuper -r 35EC92A0D72 (or just delete it, s/-r/-d/, and try another test.) http://www.postfix.org/postsuper.1.html > Nov 16 12:30:52 dur dovecot: lda(root): Error: chdir(/root) failed: > Permission denied > Nov 16 12:30:52 dur dovecot: lda(root): Error: user root: > Initialization failed: Initializing mail storage from mail_location > setting failed: stat(/root/Maildir) failed: Permission denied > (euid=65534(nobody) egid=65534(nogroup) missing +x perm: /root, dir > owned by 0:0 mode=0700) > Nov 16 12:30:52 dur dovecot: lda(root): Fatal: Invalid user settings. > Refer to server log for more information. > Nov 16 12:30:52 dur postfix/local[4134]: 35EC92A0D72: > to=, relay=local, delay=25, > delays=25/0.02/0/0.12, dsn=4.3.0, status=deferred (temporary failure) > Nov 16 12:30:56 dur postfix/smtpd[4113]: disconnect from > localhost[127.0.0.1] > root@dur:/etc/postfix# -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

I ran dovecot -a and the blizzard of data seemed ok to my limited knowledge. Is there another log I should look into to trace this error down?
