hello guys,
thanks for the suggestions. but with regards to the switching of pc and ip
address, the client would be liable for that. i think if we are going to use
the /etc/mail files of sendmail. it will surely filter the relaying and use
of sendmail. BUT remember the remaining 30 clients must use also relaying
and sendmail for them to be able to send and receive local emails.
considering on migrating to postfix if that would do the trick.. :-) BTW can
qmail do this?
thanks,
allan
