Problems with tcpserver for relaying

[Diego Puertas]

I am trying to implement selective relay for a range of IP adresses, so
when I execute the following command:

    /usr/local/bin/tcpserver -R -x/etc/tcprules.d/qmail-smtpd.cdb \
    -c100 -u81 -g80 0 smtp /var/qmail/bin/qmail-smtpd &

to activate tcpserver, tcpserver returns this error:

    tcpserver: fatal: unable to bind: address allready used

I have allready created the .cdb file with tcprules, comented the smtp
line in inet.d and restarted it.

 �What is the problem?

Thanks
