thanks Matthew Martin.
you give me important hints .
i rewrite main.cf
--------------------
/etc/postfix/main.cf
myhostname = abc.vs.sakura.ne.jp
mydomain = vs.sakura.ne.jp
myorigin = $myhostname
inet_interfaces = all
home_mailbox = Maildir/
relay_domains = $mydestination #<-
relayhost = #<-
mynetworks = 127.0.0.0/8 #<-
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain #<-
queue_directory = /var/spool/postfix
command_directory = /usr/local/sbin
daemon_directory = /usr/local/libexec/postfix
data_directory = /var/postfix
mail_owner = _postfix
inet_protocols = all
unknown_local_recipient_reject_code = 550
debug_peer_level = 2
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/local/sbin/sendmail
newaliases_path = /usr/local/sbin/newaliases
mailq_path = /usr/local/sbin/mailq
setgid_group = _postdrop
html_directory = /usr/local/share/doc/postfix/html
manpage_directory = /usr/local/man
sample_directory = /etc/postfix
readme_directory = /usr/local/share/doc/postfix/readme
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/isp_auth
smtp_sasl_security_options = noanonymous
disable_dns_lookups = yes
then i can send the srver via KEITAI(pocket phone ?)
but i cannot send mail by PC .
i guess the cause of not sending mail is company's router
beause
/var/log/maillog says
