Hi Gordon just to draw your attention to your documentation on the global_spam_virus file. ---------------------snip-------------------------------------- # If, on the other hand your backup MX servers are not running Exim4U then, on the primary Exim4U # installation, add the backup MX server to /etc/exim/exim4U_backup_mx_rl_host_names (instead of # exim4u_backup_mx_host_names) which will cause all relayed mail to be filtered for spam but # exempted from ratelimit checks. --------------------------------------------------------------------------- i realize if you set a backup host on this file, when message from "Verify sender hosts for selected large ISPs" and relay to the primary host server the emails are discarded as fake domain accounts because they messages are coming from your backup host and not one of the large mail providers like hotmail. i though i might just let you know. Thanks Kebba
