maildir delivery failed: create ... ?

This entries I find sometimes in mail.info:

Code:

Apr  6 08:42:36 server1 postfix/local[19112]: B3CD91F698: to=<[email protected]>, relay=local, delay=4, status=bounced (maildir delivery failed: create /var/spool/uucp/Maildir/tmp/1175841756.P19112.server1.de: Permission denied)

I'm right in the assumption that postfix is accepting this mail at first, than trying to create somthing (I don't understand what an whatfor) and at least after the mail is already passed through the "Permission denied" arrise?

 

Postfix tries to create the Maildir directory for the user uucp. What's the output of

Code:

grep uucp /etc/passwd

and

Code:

ls -la /var/spool/uucp

?

 

Code:

server01:~# grep uucp /etc/passwd
uucp:x:10:10:uucp:/var/spool/uucp:/bin/sh

Code:

server01:~# ls -la /var/spool/uucp
ls: /var/spool/uucp: No such file or directory

 

Do this:

Code:

mkdir -p /var/spool/uucp
chown uucp /var/spool/uucp

 

Do I realy need this directory? What for do I need it? What is the [email protected] mails?

 

Yes, if you want to receive emails for uucp. But you could also create an alias for uucp in /etc/aliases so that someone else receives those mails. In that case you don't need the uucp directory.
