[Comm] помогите, плиз с postfixом

[Алексей Данилович]

Имею следущий конфиг:

myhostname = mail.domain.su
mydomain = domain.su
inet_interfaces = 127.0.0.1, 192.168.0.1, 213.xxx.xxx.xxx
mydestination = localhost, $myhostname, localhost.$mydomain, 
$config_directory/mydestination, $mydomain
unknown_local_recipient_reject_code = 550

mynetworks = $config_directory/mynetworks
alias_maps = hash:/etc/postfix/aliases
alias_database = hash:/etc/postfix/aliases
mailbox_command = /usr/bin/procmail -a $DOMAIN -d $LOGNAME
smtpd_banner = $myhostname ESMTP $mail_name
smtpd_helo_required = yes

readme_directory = /etc/postfix/README_FILES
sample_directory = /etc/postfix/samples
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
command_directory = /usr/sbin
manpage_directory = /usr/share/man
daemon_directory = /usr/lib/postfix
newaliases_path = /usr/bin/newaliases
mailq_path = /usr/bin/mailq
queue_directory = /var/spool/postfix
mail_owner = postfix

/etc/mynetworks:
127.0.0.1/8, 192.168.0.0/24, 213.xxx.xxx.xxx/32

При этом: telnet localhost 25 (любой другой интерфейс тоже) говорит, что 
connection refused.

в чем тут дело может быть?
