利用DDNS建立POSTFIX邮件服务器的问题?

guohaili

我的环境是这样的,用的是网通的1M ADSL,接TPLINK-R402M的宽带路由器,在连一台IP:192.168.1.100的LINUX AS4的系统,我想在这台机器用www.3322.org提供的动态域名(我申请的的动态域名是ipcmail.3322.org)建立一个邮件服务器实现内外部收发信的功能,在宽带路由器上我已经把25和110 端口都影射给192.168.1.100这台机器,经过从外网测试也证明了这两个端口确实打开了,而且POSTFIX的内部收发邮件已经没有问题,我现在想用这个邮件服务器来给其他邮件服务器如mail.163.com发信,但是总是发送不成功,不知道是什么原因,还请各位大侠帮帮忙看看!!!!!!!
以下是我的POSTFIX MAIN.CF和DOVECOT.CONF的配置文件

[root@localhost firefox]# 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
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, $mydomain, mail.$mydomain, www.$mydomain, ftp.$mydomain
mydomain = ipcmail.3322.org
myhostname = 3322.org
mynetworks = host
myorigin = 3322.org
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.1.5/README_FILES
sample_directory = /usr/share/doc/postfix-2.1.5/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
unknown_local_recipient_reject_code = 550
[root@localhost firefox]#




[root@localhost firefox]#vi /etc/dovecot.conf
protocols = imap imaps pop3 pop3s
imap_listen = [::]
pop3_listen = [::]
login = imap
login = pop3
mbox_locks = fcntl
auth_passdb=shadow

现在我的邮箱能收发内外邮箱了,但是新的问题有出现了
我用我外部邮箱给我的ipcmail.3322.org任何一个帐号发信时,我在主机不能自动刷新,我就手动刷新一下吧,但是一下子就出现错误信息了
