    Sendmail server


    Hello all,
    Please i'm trying to set up a sendmail server for my intranet.I have edited my sendmail.mc and have started sendmail.The problem i have is that the windows client behind the sendmail server cannot locate the SMTP server.Moreover,i typed the command netstat -an |grep :25 and it did not bring out any output.I think something is wrong with my configuration file.Please can someone help me on getting Microsoft outlook to send and recieve mails within the intranet on the sendmail server.Below is my sendmail.cf file.

    # CacheEnable disk /
    # CacheRoot "/var/cache/mod_proxy"
    #</IfModule>
    #

    #</IfModule>
    # End of proxy directives.

    ### Section 3: Virtual Hosts
    #
    # VirtualHost: If you want to maintain multiple domains/hostnames on your
    # machine you can setup VirtualHost containers for them. Most configurations
    # use only name-based virtual hosts so the server doesn't need to worry about
    # IP addresses. This is indicated by the asterisks in the directives below.
    #
    # Please see the documentation at
    # <URL:http://httpd.apache.org/docs-2.0/vhosts/>
    # for further details before you try to setup virtual hosts.
    #
    # You may use the command line option '-S' to verify your virtual host
    # configuration.

    #
    # Use name-based virtual hosting.
    #
    #NameVirtualHost *:80
    #
    # NOTE: NameVirtualHost cannot be used without a port specifier
    # (e.g. :80) if mod_ssl is being used, due to the nature of the
    # SSL protocol.
    #

    #
    # VirtualHost example:
    # Almost any Apache directive may go into a VirtualHost container.
    # The first VirtualHost section is used for requests without a known
    # server name.
    #
    #<VirtualHost *:80>
    # ServerAdmin webmaster@dummy-host.example.com
    # DocumentRoot /www/docs/dummy-host.example.com
    # ServerName dummy-host.example.com
    # ErrorLog logs/dummy-host.example.com-error_log
    # CustomLog logs/dummy-host.example.com-access_log common

    Seeme:

    If you have a question, please post in your own thread in the appropriate forum (looks like Servers in this case). Hijacking threads is against the rules.

    Why sendmail?

    I don't mean to sound like a elitist snob (because, really, I'm not one) but I've dealt with sendmail for a long time. I hate it, personally. I've recently turned to PostFix for all my needs and it works great. An excellent how to can be found here:

    http://www.howtoforge.com/perfect_setup_fedora_core_5

    You don't have to do all of it, just the Postfix part. Works great.

    Edit: I use this at home and at work for handling thousands of mails a day.
