    I installed FC4 as a mail server. Then I used Outlook to test it. The POP3 (incoming email) was passed, however, the outgoing (SMTP, port 25) failed. I got the error message:
    The TCP/IP connection was unexpectedly terminated by the server.(server: '192.168.2.214', Error Number 0x800ccc0f).

    I checked the server using nmap localhost, I got the following output:
    Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2006-03-30 16:36 EST
    Interesting ports on mail1.avensys.ca (127.0.0.1):
    (The 1652 ports scanned but not shown below are in state: closed)
    PORT STATE SERVICE
    21/tcp open ftp
    22/tcp open ssh
    25/tcp open smtp
    80/tcp open http
    110/tcp open pop3
    111/tcp open rpcbind
    143/tcp open imap
    443/tcp open https
    993/tcp open imaps
    995/tcp open pop3s
    3306/tcp open mysql

    It seems that smtp port 25 is open.

    I also use netstat -tap to get the following result:
    Active Internet connections (servers and established)
    Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

    I saw smtp was listening.
    What's wrong with me? Any suggestion?
    Thanks a lot.

    Did you get any errors in your mail log?

    The mail log in /var/log/maillog likes this:

    What does the 'Mailbox vulnerable - directory /var/spool/mail must have 1777 protection' mean?

    Thanks.

    Please run
    Code:
    chmod 1777 /var/spool/mail
    However, this does not affect your sending problem. Can you post a log excerpt from when you try to send a mail?

    I can deliver mail within local machine. For example, use command line:
    [[email protected] ~]# mail paul
    the account paul can receive the test mail. I can see this in maillog file:

    Mar 23 09:37:15 mail1 postfix/pickup[13761]: 19004290F9B: uid=500 from=<zyan>

    Mar 23 09:37:15 mail1 postfix/local[13843]: 19004290F9B: to=<[email protected]>, orig_to=<paul>, relay=local, delay=0, status=sent (delivered to mailbox)
    Mar 23 09:37:15 mail1 postfix/qmgr[1945]: 19004290F9B: removed

    I just found some errors in the /var/log/maillog file, but only occurred from yesterday:
    Mar 31 01:38:43 mail1 postfix/qmgr[3015]: 38838290F9B: from=<[email protected]>, size=295, nrcpt=1 (queue active)

    Mar 31 01:38:44 mail1 postfix/master[1937]: warning: /usr/libexec/postfix/smtp: bad command startup -- throttling

    How to solve it?

    Please post your /etc/postfix/master.cf and the output of
    Code:
    grep -i smtp /etc/services

    Looks ok...
    What's the output of
    Code:
    ls -la /usr/lib/postfix

    No such file on my machine.
    I issued command: find / -name postfix -print
    the ouptput:
    Something wrong with my system files?

    Does /var/spool/postfix/etc/services exist? Your smtpd daemon is running chrooted.
