    hi ya

    to the poster that posted about "step by step" process
    to setup an email server ...
            - i deleted your mail .. and decided to reply now

    lets see ...

    0) harden your mail server to minimize exploitable vulnerabilities
            http://www.debian.org/doc/manuals/securing-debian-howto/
            http://www.Linux-Sec.net/Harden/

    a) pick which mta you like
            - sendmail, exim, postfix, qmail, foo
            http://www.Linux-Sec.net/Mail/#MTA

            ( lets make it easy and use exim if you're using
            ( a debian box

    b) pick what you want it to do ..
            - configure it for antispam
            http://www.Linux-Sec.net/Mail/AntiSpam/
                    - rbls, reverse dns,
                    - fake users sending and receiving
                    - bad headers, bad subject, bad content,
                    - blah blah to filter against

            - configure it for antivirus
            http://www.Linux-Sec.net/Mail/AntiVirus/

            - configure it for foo-features
            - think you wanted ldap features too ??
            ( shy ?? )

    c) pick which pop server you want
            - imap ??? ( bad choice )

            - use secure imap instead
            http://linux-sec.net/Mail/secure_pop3.gwif.html

    d) play with apt-get options to see whats available in *.deb packages

    e) webmail vs ldap ?? ( anybody can check email from anywhere )
            - i'd pick secure webmail instead
            http://www.Linux-Sec.net/Mail/#WebMail

    f) configure samba if you have windoze users

    c ya
