Question RHEL6 sendmail & postfix can't use local user


Hi All,

I've tried to configure the mail service in RHEL6 but seems both sendmail and postfix can't use local user located in /etc/passwd.

Like, user Tommy and Jake they got User Unknow from maillog
Tommy:x:506:507::/home/Tommy:/bin/bash
Jake:x:507:508::/home/Jake:/bin/bash

But IF I use users' home folder not located in /home then it can go throught...
mailuser2:x:513:514::/rhome/mailuser/mailuser2:/bin/bash
mailuser3:x:514:515::/rhome/mailuser/mailuser3:/bin/bash

/var/log/maillog stat=User unknown from Tommy and Jake(using postfix),
Jul 3 14:48:07 mail sendmail[7583]: p636m7Ql007583: from=Tommy, size=212, class=0, nrcpts=1, msgid=<201107030648.p636m7Ql007583@mail.example.com>, relay=Tommy@localhost

[root@mail ~]# rpm -qa | grep sendmail
sendmail-8.14.4-8.el6.x86_64
[root@mail ~]# rpm -qa | grep postfix
postfix-2.6.6-2.el6.x86_64

Do someone know the what's the reason of local user cannot be used?

have you asked red hat ?
you did buy a license -right
that also has tech support
http://www.redhat.com/support/
https://access.redhat.com/knowledge/docs/
or at least access to the red hat database
https://access.redhat.com/knowledge/search

most things will require the use of the user name and password you set when you bought and authorized your RHEL6 install.
