On the latter point first, I don't think SA looks at all IP's in the headers. Using the trusted_networks configuration parameters, you can tell it whhich Received lines it can trust. It will then check the incoming IP's on those lines, but I don't recall whether it does RBL checking on those lines by default. SA also does RBL checking on IP addresses derived from URL's in the message body, which is something that would be quite a bit of work for MdF. We do use RBL's via sendmail's access list, using a program called spfilter to build up those access lists from known user-selectable RBL's sources. It works well. - Gary _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID. You may ignore it.
