Why can't send mail with command mail or mailx?

August 19, 2015 2.8k views

I have installed postfix and start postfix service .

I can send email from user root to user debian8 by telnet command.

root@pengsir:/home/debian8# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 pengsir.hfi ESMTP Postfix (Debian/GNU)
ehlo mail
250-SIZE 10240000
250 DSN
mail from:<root>
250 2.1.0 Ok
rcpt to:<debian8>
250 2.1.5 Ok
354 End data with <CR><LF>.<CR><LF>
this is a test mail send from root
250 2.0.0 Ok: queued as CA53CF82C3
221 2.0.0 Bye
Connection closed by foreign host.

Let's change user debian8 to receive the email.

root@pengsir:/home/debian8# su debian8
debian8@pengsir:~$ mail
Mail version 8.1.2 01/15/2001.  Type ? for help.
"/var/mail/debian8": 1 messages 1 new 1 unread
 N  1 root@pengsir.hfi   Wed Aug 19 10:10   13/441   
& 1
Message 1:

From: root@pengsir.hfi

this is a test mail send from root

& quit

It is strange that i can not send email with mail or mailx command.

mail -s 'test_for_postfix'  debian8@pengsir.hfi
mailx -s 'test_for_postfix'  debian8@pengsir.hfi

It look like that the cursor will be stop in the console forever ,no error info putput when to execute the two commands.
