Hi, since I do not have a nameserver for the FreeBSD 5.4 (do not
want to configure one, either), the sendmail complains that the
host name is not a valid one. Could someone let me know how to
silence this guy (sendmail)?
Here is what is happening:
I configured rc.conf not letting it to start at boot time (and it
looks like it does not), however, every night something like 3am,
the sendmail still dumps information on tty0 complaining about
the domain name.

不知道BSD上具体是怎么配置,但是在Linux上, 你不一定需要在服务器上安装
DNS服务,但是至少你要指定一个外部的DNS给服务器上的各种服务使用. 否则你的
邮件服务器怎么知道如何送信呢?
另外一个可能考虑的地方是关掉Sendmail反向域名查询的功能, 这样可能带来
一些伪造地址的邮件.

My computer is on privite (192.168.0.*) network, and I only use it
for simulations. Because the stupid IT policy, it cannot go to the
internet, and hence no DNS accessible, and I do not want one on the
machine just for sendmail.
Also, my computer domain name is not registered to any DNS (there is
not any DNS, infact). This sendmail is default installation.
I know I can configure the sendmail to let it stop complaining. However,
given my tight time schedule, no interest in figuring it out.
So wha

如果你的Sendmail不收也不发, 那关掉就行了吧?

That's what I wanted. How to do that? I am not quite good
at FreeBSD configurations.
I thought if in rc.config not to let sendmail to start, it
should not... But why it still complains every night at
around 3am?

Hey, Terminator,
This time I am a little better than last time.
I first "manned" cron, and found it has two places
for its "tables". However, I could not find anything
related to sendmail. In fact, /ect/crontab is the file
I checked, and the one mensioned in man page, the /var/...
one is not even there.
So can you give me more info?
