Once in a while i get some SPAM, but once they get in I check the email header and block their mail server via iptables. I also use tcpserver like this, not sure if this is the best way, but it seems to work => /usr/local/bin/tcpserver -p -v \ -x/var/qmail/control/tcp.smtp.cdb -u<your UID> -g<your GID> 0 smtp \ /usr/local/bin/rblsmtpd -r relays.osirusoft.com -r relays.ordb.org -r \ orbs.gst-group.co.uk /var/qmail/bin/qmail-smtpd 2>&1 & Some spamer are harder to get than others, because they have many mail servers (i.e. many IPs). For these I use procmail to filter SPAM using the doamin name of the mail server of the spammer. ::dc:: David Correa RHCE CCNA _ _ _ _ _ _ _ _ ___ ____ ____ _ _ tech@linux-tech.com | | |\ | | | \/ | |___ | |__| http://www.linux-tech.com |___ | | \| |__| _/\_ | |___ |___ | | ------------------------------------------------------------------------ To unsubscribe email security-discuss-request@linuxsecurity.com with "unsubscribe" in the subject of the message.
