sendmail log中这句何意？

Question

May 21 15:16:07 traveller2 sendmail[3414]: k4L7FpHl003414: [172.16.198.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

试验配置mail server，域名、relay等都已经设置好，用 mozilla thunder bird 可以收信，但是却无法发信，现象是不停弹出窗口让问输入密码，输入后也不管用。从[172.16.198.1] 可以telnet mail server的25端口。

第一次配mail，不懂。

Answer 1

AUTH DIGEST-MD5 CRAM-MD5      应该是plan？？

Answer 2

我的也是这样,不过在客户端的OUTLOOK如果需认证服务就会出现输入密码的窗口, 不需要认证就可以发但是都不可以收!真是急死人了!

Answer 3

没有打开这个 service saslauthd start
但是打开后虽然send设置的是需认证服务，但 outlook 无论设不设置认证都可以随便发信。

Answer 4

防火墙没开，查了很久资料也没找到头绪

Answer 5

会不会是防火墙的问题？

莫非是客户端的问题？
