It would work -- but usually Exim already includes the tcpd stuff, so that Exim *automagically* uses /etc/hosts.(allow,deny). You don't need to prefix the inetd.conf line with "tcpd". But note that this is only of limited use -- spammers change IP addresses and SMTP relays often, so blocking them doesn't give you any benefits. You might even block legitimate messages from being delivered! Better have a look at procmail (Debian package available.) This allows you to filter messages by their (header and body) contents -- probably more what you want than the above. -- Verkaufe Original-BMW-Raeder: L I N U X .~. http://adsl-bergs.rz.rwth-aachen.de/~rabe The Choice /V\ of a GNU /( )\ Generation ^^-^^
