LinuxQuestions.org - postfix

Hi,
i want to setting up my postfix for my domain and for the localhost users.

this is my config of main.cf

Code:

queue_directory = /var/spool/postfix

command_directory = /usr/sbin

daemon_directory = /usr/libexec/postfix

mail_owner = postfix

mydomain = segalsites.org

inet_interfaces = localhost

mydestination=$myhostname,localhost.$mydomain,localhost,$mydomain

unknown_local_recipient_reject_code = 550

alias_maps = hash:/etc/aliases

alias_database = hash:/etc/aliases

debug_peer_level = 2

debugger_command =

PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin

xxgdb $daemon_directory/$process_name $process_id & sleep 5

sendmail_path = /usr/sbin/sendmail.postfix

newaliases_path = /usr/bin/newaliases.postfix

mailq_path = /usr/bin/mailq.postfix

setgid_group = postdrop

html_directory = no

manpage_directory = /usr/share/man

sample_directory = /usr/share/doc/postfix-2.1.5/samples

readme_directory = /usr/share/doc/postfix-2.1.5/README_FILES

when i try :

Code:

echo hi | sendmail -f root root && tail -50 /var/log/maillog > `tty`

i get the next result :

Code:
