在郵件服務(wù)器上使用root給mysql用戶發(fā)郵件，
[root@mail named]# telnet localhost 25

日志中打印以下信息

執(zhí)行nslookup，結(jié)果如下：
[root@mail named]# nslookup

看了下各位大大以前的貼子。發(fā)現(xiàn)是說disbaled_nslookup=yes引起的，我執(zhí)行了以下命令，結(jié)果如下：
[root@mail named]# postconf |grep relay_domains
fast_flush_domains = $relay_domains
parent_domain_matches_subdomains = debug_peer_list,fast_flush_domains,mynetworks,permit_mx_backup_networks,qmqpd_authorized_clients,relay_domains,smtpd_access_maps
proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks
relay_domains = $mydestination
relay_domains_reject_code = 554


[root@mail named]# postconf |grep lookup
disable_dns_lookups = no
ignore_mx_lookup_error = no
lmtp_host_lookup = dns
smtp_host_lookup = dns
smtpd_null_access_lookup_key = <>
smtpd_peername_lookup = yes

所以不知道原因了。。。請各位大大和高手們，幫忙看下。。搞了3天了。謝謝。

哦，問題找到了。。之前IP變更時，/etc/hosts文件中的IP沒有改。。
另外，還有就是我在DNS中配置的那個網(wǎng)口，沒有啟動成功。
