    running as root. Instead it impersonates itself to the same UID and GID
    that sendmail uses for delivering mails. In what follows, I assume UID
    *daemon* and GID <mail>, as used on a Red Hat Linux box.

    IspMailGate needs its own directory for creating temporary files.
    Usually this could be `/var/spool/ispmailgate' or something similar.
    Make sure that the daemon user from above, (but noone else) has access
    to this directory:

        mkdir /var/spool/ispmailgate
        chown daemon /var/spool/ispmailgate
        chgrp mail /var/spool/ispmailgate
        chmod 700 /var/spool/ispmailgate

  Program installation

    The program is installable like any other Perl module. Indeed, you can
    even use the automatic CPAN installation. If you are not used to CPAN
    installation or cannot use the CPAN shell, you need to perform a manual
    installation: First, fetch the archive from any CPAN mirror, for example

        You see, the only difference between these two instances of
        mailertable is that the domain *ispsoft.de* is treated different.

    Finally we have to execute some commands to get this configuration
    running:

            mkdir /var/spool/mqueue2
            # The following should match the settings of
            # /var/spool/mqueue exactly.
            chown root /var/spool/mqueue2
            chgrp root /var/spool/mqueue2
            chmod 755 /var/spool/mqueue

            cd /etc/mail
            m4 sendmail.mc >sendmail.cf
            makemap hash mailertable <mailertable
            cd /etc/mail2
            m4 sendmail.mc >sendmail.cf
            makemap hash mailertable <mailertable

IspMailGate needs its own directory for creating temporary files.
Usually this could be C</var/spool/ispmailgate> or something
similar. Make sure that the daemon user from above, (but noone else)

	chown root /var/spool/mqueue2

might be more appropriate.

Do not forget to set the file permissions the right way. For example you
might do the following:

    su
    mkdir ~ispmailgate/.pgp
    cp ~info/.pgp/pubring.pgp ~ispmailgate/.pgp
    cp ~info/.pgp/secring.pgp ~ispmailgate/.pgp
    cp ~info/.pgp/randseed.bin ~ispmailgate/.pgp
    chown -R ispmailgate ~ispmailgate/.pgp
    chgrp -R ispmailgate ~ispmailgate/.pgp
    chmod 755 ~ispmailgate/.pgp
    chmod 600 ~ispmailgate/.pgp/*

If you don't have an appropriate keyring, you can instead create a new
one. This is done with the following command:

    su - ispmailgate -c "pgp -kg"

PGP will ask you some questions, for example:
