sendmail启动后出现的问题，希望哪位朋友指教
网络内部服务器的ip为192.168.0.249，安装的RHEL AS 3 U6，同时配置了named、vsftpd和sendmail，DNS和vsftpd都正常，就是sendmail配置完，只能在服务器上可以收发邮件，可是在客户端用outlook 就不行提示如下：
您的服务器意外终止了连接。其可能原因包括服务器出错、网络出错或长时间处于非活动状态。 帐户: '192.168.0.249', 服务器: '192.168.0.249', 协议: POP3, 端口: 110, 安全(SSL): 否, 错误号: 0x800CCC0F
# host -t MX yjs.com
yjs.com mail is handled by 10 mail.yjs.com.
# host mail.yjs.com
mail.yjs.com has address 192.168.0.249
可以在服务上收发邮件：
# telnet mail.yjs.com 25
Trying 192.168.0.249...
telnet: Unable to connect to remote host: Connection refused

# netstat -tnl |grep :25

（这里的 localhost.localdomain 应该是内部域名mai.yjs.com才对吧？）

named和sendmail都已经启动了：
# ps aux |grep named

这个问题困扰的实在是搞不明白了，请朋友们帮帮我，十分感谢。 想在客户端用邮件收发工具收发邮件是需要服务器安装pop3协议的,看看你的Sendmail服务器安装了POP3邮局协议没啊?最好能把IMAP4协议也一起装好,他能够很好的和微软的邮件客户端提供支持,建议你安装后在检查!!
