The "postmaster" is a virtual account

In my aliases file you should find

mailer-daemon:  postmaster
postmaster: root

"root" is the administrator in Linux, which has existing account.


So you should do it...

create your own account at first
e.g. username = john

1. add the following into aliases file
   "root: john"

2. Type "newaliases" in text mode

Then all mails of "postmaster" & "root" will be send to john's mail account

I hope it can help.

I think its the "newaliases" command you have forgotten, it applies the changes you made to the deamon.

I assume you arent using postfix? Postfix wont deliver mail to root.

Problem 1)

When I send out a test email, out of the server to blank@rgrtrrtetete.com   --> invaild account

I do not get a "Mail Delivery Subsystem [MAILER-DAEMON@" return like I would emailing out of yahoo or something.
Am I suppose to?
When I look in mailq it is not in there?

Problem 2)
Root is not getting the returen either? Do I have to wait longer or is there some setting I need to tweak to get the return?

Have you got a
localhost 127.0.0.1
line in your /etc/hosts file? It looks like your hostname is setup wrong. relay=rgrtrrtetete.com rgrtrrtetete.com is a domain, not a machine.

(Host File)
/etc/hosts
127.0.0.1               servername rgrtrrtetete.com

(DNS setup ?)
cat /etc/sysconfig/networking/porofiles/default/resolv.conf
nameserver 2xx.xxx.xxx.xxx

(Make sure your created account 'mailreturn' & 'root' account are worked or not ?)
mail -u root
mail -u mailreturn

Or even sendmail services is started as normal ?

Give us the log entry for the incoming MAILER-DAEMON@ part instead.

FYI

I use to have it set up like this

# Basic system aliases -- these MUST be present.
mailer-daemon:  postmaster
postmaster:     root

Root did get the mail returns.

then i changed to this

# Basic system aliases -- these MUST be present.
mailer-daemon:  postmaster
postmaster:     mailreturn

and mailreturn doesn't work

It should be correct, so you try it...

1. userdel mailreturn
2. 'rm /var/spool/mail/mailreturn' & 'rm /home/mailreturn'
3. useradd mailreturn again
4. And make sure mailreturn account is worked by mail testing
5. Then edit aliases file and run "newaliases"
