It's actually a Postfix problem. Postfix is invoking your Dovecot LDA with wrong permissions. > Dovecot and system info: > > thufir@dur:~$ > thufir@dur:~$ dovecot --version > 2.0.19 > thufir@dur:~$ > thufir@dur:~$ cat /etc/lsb-release > DISTRIB_ID=Ubuntu > DISTRIB_RELEASE=12.04 > DISTRIB_CODENAME=precise > DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS" > thufir@dur:~$ > > testing postfix & dovecot > (http://packages.ubuntu.com/precise/dovecot-postfix): > > root@dur:/etc/postfix# > root@dur:/etc/postfix# telnet localhost 25 > Trying 127.0.0.1... > Connected to localhost. > Escape character is '^]'. > 220 dur.bounceme.net ESMTP Postfix (Ubuntu) > helo me > 250 dur.bounceme.net > mail from:[email protected] Angle brackets are required on envelope addresses (and I bet you don't own bar.com): MAIL FROM:<[email protected]> > 250 2.1.0 Ok > rcpt to:[email protected] RCPT TO:<[email protected]> > 250 2.1.5 Ok > data > 354 End data with <CR><LF>.<CR><LF> > subject:ping 3 > blah blah > . A header must have a space after the colon. Header and body are separated by a blank line.

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=<[email protected]>, 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:
