This is easiest to manage if you have one mail gate and everything behind the firewall uses it as the smart host. | I'd be interested to hear Rats or others views of what I should be doing | regarding From and sender. (Message-ID would be a bonus). >>From should be reader@newsguy.com. Sender should start out being something appropriate for the sending machine inside your firewall, and be masqeraded (and possibly rewritten entirely) by your mail gate with your One True FQDN associated with your single IP address. Message-ID strings can be simpler or harder, depending on how militant one is. The one absolute requirement is that any given message's Message-ID be unique. Usually the easiest way to accomplish this is to hash/mash login, FQDN and time stamp. You might be better off telling Gnus not to generate Message-ID strings either, and let your mail gate handle it. -- Rat \ If Happy Fun Ball begins to smoke, get Minion of Nathan - Nathan says Hi! \ away immediately.
