postfix 无法接收邮件？

maillog 日志如下：
Dec 4 03:58:06 mail postfix/smtp[4361]: 8CF5C1D0419: to=<wendy@newprecise.local>, relay=newprecise.local[60.191.124.236]:25, delay=20, delays=0.04/0.01/20/0, dsn=4.0.0, status=deferred (host newprecise.local[60.191.124.236] refused to talk to me: 421 Cannot connect to SMTP server 60.191.124.236 (60.191.124.236:25), connect timeout)
postconf -n 如下：
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/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 = $myhostname, localhost.$mydomain, localhost
mynetworks = 192.168.154.0/24 127.0.0.0/8
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
sample_directory = /usr/share/doc/postfix-2.3.3/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
unknown_local_recipient_reject_code = 550
virtual_alias_maps = mysql:/etc/postfix/mysql-aliases.cf
virtual_gid_maps = static:89
virtual_mailbox_base = /home/postfix
virtual_mailbox_domains = mysql:/etc/postfix/mysql-domains.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql-users.cf
virtual_uid_maps = static:89

我只是在虚拟机中做的测试，邮件可以发送，就是收不了。
环境如下：postfix,mysql,dovocet，apache，
请各位帮忙。
