Hi everyone,
I have a strange problem with postfix. It is setup for use on a single host, but should recieve mail for all local users. I set everything up according to the comments in main.cf. I have not yet setup a chroot environment in master.cf.
Email for local users gets bounced all the time. I tested by sending emails from an external account to a local user. Error messages in mail.log are the same (xxx is replacing the real values):
Feb 20 18:56:34 rc postfix/smtpd[16295]: connect from unknown[217.72.192.151]
Feb 20 18:56:34 rc postfix/smtpd[16295]: A633837208: client=unknown[217.72.192.151]
Feb 20 18:56:34 rc postfix/smtpd[16295]: warning: cannot access UNIX password database: Permission denied
Feb 20 18:56:34 rc postfix/smtpd[16295]: A633837208: reject: RCPT from unknown[217.72.192.151]: 451 <xx@xxx.xxx.xxx>: Temporary loo
kup failure; from=<xxxx.xxxxx@web.de> proto=ESMTP helo=<smtp.web.de>
Feb 20 18:56:36 rc postfix/cleanup[16298]: C19AE3720B: message-id=<20030220185636.C19AE3720B@xxx.xxx.xxx>
Feb 20 18:56:36 rc postfix/qmgr[16283]: C19AE3720B: from=<double-bounce@xxx.xxx.xxx>, size=794, nrcpt=1 (queue active)
Feb 20 18:56:36 rc postfix/smtpd[16295]: disconnect from unknown[217.72.192.151]
Feb 20 18:56:36 rc postfix/local[16299]: C19AE3720B: to=<root@rc.mine.nu>, orig_to=<postmaster>, relay=local, delay=0, status=deferred (SOFT BOUNCE - unknown user: "root")
I am sure that the user exists, and I do not understand why postfix complains, that it cannot access the unix password database (which I suppose is the reason why both the local user and root are unknown). It is a standard gentoo installation. As far as I understand, no special USE settings. I have not changed any permissions. I have set mail_owner = mail
Any ideas?
Thanks,
Corty |

Hello,
did you setup postfix chrooted?
who owns the /var/spool/postfix directory and subdirectories?
best regards

This is my postfix master.cf (unchanged from the default install):
| Code: | ==========================================================================
# service type private unpriv chroot wakeup maxproc command + args
# (yes) (yes) (yes) (never) (100)
# ==========================================================================
smtp inet n - n - - smtpd
#smtps inet n - n - - smtpd
# -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes
#submission inet n - n - - smtpd
# -o smtpd_enforce_tls=yes -o smtpd_sasl_auth_enable=yes
#628 inet n - n - - qmqpd
pickup fifo n - n 60 1 pickup
cleanup unix n - n - 0 cleanup
qmgr fifo n - n 300 1 qmgr
#qmgr fifo n - n 300 1 nqmgr
#tlsmgr fifo - - n 300 1 tlsmgr
rewrite unix - - n - - trivial-rewrite

showq unix n - n - - showq
error unix - - n - - error
local unix - n n - - local
virtual unix - n n - - virtual
lmtp unix - - n - - lmtp |
As far as I understand it (I am new to postfix), I am not running it in a chrooted environment. I also checked ownership of passwd and /etc, both are world readable.
/var/spool/postfix is owned by root.root (0755). Directories within:
| Code: | drwx------ 15 mail root 256 Feb 20 21:53 active
drwx------ 2 mail root 35 Feb 20 19:54 bounce
drwx------ 2 mail root 35 Feb 20 19:54 corrupt
drwx------ 15 mail root 256 Feb 20 21:53 defer
drwx------ 15 mail root 256 Feb 20 21:53 deferred
drwx------ 2 mail root 35 Feb 20 19:54 flush
drwx------ 2 mail root 35 Feb 20 19:54 hold
drwx------ 16 mail root 273 Feb 21 09:03 incoming
drwx-wx--- 2 mail postdrop 35 Feb 21 09:03 maildrop
drwxr-xr-x 2 root root 166 Feb 20 19:56 pid
drwx------ 2 mail root 384 Feb 20 19:54 private
drwx--x--- 2 mail postdrop 142 Feb 20 19:54 public
drwxr-xr-x 2 root root 35 Feb 20 19:53 tmp |
I have to be honest: I absolutely have no clue...
Thanks for your help.

Hello,
As of version 2, postfix now uses the proxymap service to read the receipient maps (this simplified chrooting amongst other things). You need to change your local_receipient_maps to:
| Code: | | local_recipient_maps = proxy:unix:passwd.byname $alias_maps |
This should fix your issues. For more info please read the release notes: /usr/share/doc/postfix-2.0.3/RELEASE_NOTES.gz
Thanks, |

Hello again,
I now have
| Code: | | local_recipient_maps = proxy:unix:passwd.byname $alias_maps |
But unfortunately this does not solve the problem. Log entry:

rred (SOFT BOUNCE - unknown user: "root") |
As far as I understand the proxymap service is optional, not mandatory. Any other ideas?
Thanks for the help so far!!!

The problem has been solved through a complete new install. As I had trouble with various programs (samba, postfix), all related to authentification and file access I decided to give it another clean try. Astonishingly all work now, with exactly the same config files. I suppose something must have gone wrong with the bootstrap process, maybe glibc ... We will never know!  )
Thanks for any help!!
