hello all,
If i send mails using postfix,the mails stored in queue,not delivered to required recipient...can anyone please tell me the solution for this problem...

You have not provided any configuration details. Are you using relaying? Are you delivering to local accts?

[root@server log]# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
html_directory = no
inet_interfaces = all
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $server.example.com, localhost.$example.com, mail.$example.com
mydomain = example.com
myhostname = server.example.com
mynetworks = 192.168.0.0/24,127.0.0.0/8
myorigin = $example.com
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
unknown_local_recipient_reject_code = 550

And are you sending to your local machine (which, by the way, your configuration does not specify the machine's name or domain). How is the email server going to determine how to send the message?

ya here i configured for to test the local machine...i send the mail to another user but the mail does not delivered to recipient,that they saved in queued..
