Try checking your mail log file (/var/log/maillog), for possible problems.

signal 15 is sigkill, which if you didn't invoke it means that system is not happy about something. sounds like its crashing. Perhaps a mismatched library. Did you update recently? How is your system doing on memory? Check out /var/log/messages, perhaps it contains more information on why the postfix process is crashing.

ya its scanned everything using this command tailf /var/log/messages..

[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

Does it give you any output when restart the service?

service postfix restart

or

/etc/init.d/postfix restart

[tilakraj]

ya i restart the postfix service...postfix service is correctly restarted without error...and also i on the service using
chkconfig postfix on command..

What does your system say about the messages in the queue:

postqueue -p

you can also look for out of place variables, by turning up the debug as well.

postqueue -v

[tilakraj]

[root@server log]# postqueue -p
