Please indicate the IP addresses (ranges) that you will be doing this from. I will make sure there is an iptables DROP rule for them on all email infrastructure I control. If you use cloud infrastructure for which this approach does not make sense, please indicate the domain name(s) you will be HELOing as so that your HELOs can get a "Verifiers not welcome" response and all your requests will be denied. -- Atro Tossavainen, Chairman of the Board Infinite Mho Oy, Helsinki, Finland tel. +358-44-5000 600, http://www.infinitemho.fi/ _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
