[mramin05]

Hi guys,

I have installed postfix and Dovecot in my CentOS 5 box.

mydomainname = xxxxxx.com
myhostname = mail.xxxxxx.com

But when I send mail from my yahoo mail, The mail is not send and the reply
following message comes :

The mail system
<myownid@xxxxxx.com>: maildir delivery failed: create
maildir file
/home/myownid/Maildir/tmp/1231489707.P8212.mail.xxxxxx.com:
Permission denied

My mail directory is /home/myownid/Maildir
I have created Maildir according the tutorial
http://wiki.centos.org/HowTos/postfix
and configure the as the same
I have tried with chmod 777 /home/myownid/Maildir
but the same reply.
I have also disabled the SELINUX and reboot the machine.
>>grep SELINUX /etc/selinux/config
# SELINUX= can take one of these three values:
SELINUX=disabled

This is the output of -la
[root@mail ~]# ls -la /home/myownid/Maildir
total 40
drwxrwxrwx 5 root root 4096 Jan 9 07:08 .
