    can't I receive or send mail except from the linux box


    Redhat 7.2,

    I have sendmail up and running 8.11.6-3.

    Anyway, If I am on the Linux box I can send mail. However, If I use a windoz box to send mail I get an error.

    The connection to the server has failed. Account: 'xxxx.linux-dude.com', Server: 'xxxx.linux-dude.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

    I also get this error when mail cannot be sent.

    Deferred: Connection refused by xxxx.linux-dude.com

    But I can receive mail that was sent from the linux box to itself using the windoz box.

    Also, if I send mail from any account like hotmail or yahoo the email dissapears. it never gets to the server.

    --------------------------------------
    Sendmail config using webmin
    --------------------------------------

    I have

    local domain set
    'xxxx.linux-dude.com'

    trusted user
    myself

    outgoing domain
    'xxxx.linux-dude.com'

    relay domain
    'xxxx.linux-dude.com'

    alias
    myself.

    ----------------------------------------------------------------
    my access file looks like this

    localhost.localdomain RELAY
    localhost RELAY
    127.0.0.1 RELAY

    xx.93.xx.240 RELAY
    192.168.1.100 RELAY
    192.168.1.101 RELAY
    xxxx.linux-dude.com RELAY

    ------------------------------------------------------------------

    Any ideas?

    Thanks in advance

    1) Make sure port 25 is accepting connection to everyone except some open relay hosts where you can deny them explicity or use RBL.
    2) If your SMTP server is not SSL/TLS-aware, make sure you have disabled it in your email client

    >> If I am on the Linux box I can send mail

    For your Linux box to send outgoing messages to remote hosts, it doesn't even need to be running a SMTP server at all. Imagine you launch telnet and connect to port 25 and invoke SMTP commands manually, the other end doesn't care if you are running a SMTP server.

    >> But I can receive mail that was sent from the linux box to itself using the windoz box

    Port 25 doesn't take place at all. Checking your mail, say pop3, that's port 110, and it has nothing to do with port 25.

    Don't ask me how to configure Sendmail, because I don't know or care. Sendmail is on the top 5 of most insecure software list (BIND, Samba, webmin and wu-ftpd being the others). Redhat as well is not so secure. Running an out-of-date version (8.12.1 being the lastest) of Sendmail on Redhat makes it extremely insecure and potentially vulnerable to local and remote exploits at any time.
    Then who makes the most secure software?

    Problem solved

    sendmail.cf file coming with RH7.2 only listens on loopback interface. u can see that in netstat -an

    it looks like this

    tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN

    I Commented following option and restarted the sendmail daemon.

    O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA


    Then after restarting the daemon using netstat -an.
    the output changed to

    tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN

    My mail now works
