[cobalt-users] spam relay

["abcwebspace" <gr@xxxxxxxxxxxxxxx>]

Hi

i have someone spamming through my sendmail using a local host name etc. I
don't allow my clients to use smtp and I thought sendmail was pre-configured
not to relay mail? (RAQ3). As a temp measure I've used
/etc/rc.d/init.d/sendmail stop to shut the sendmail down - what next????

cheers

Gary
