How hard is it to allow uu.net mail relays, but no direct connections from dialups, ie: foo.tnt.foo.uu.net is blocked but smtp.uu.net is not? I'm looking to do something like this here, but haven't revisited sendmail in some time. There's no reason for a dialup connection to send me (or anyone else) mail directly. They should be sending via their ISP's relay instead. Charles Charles Sprickman spork@super-g.com ---- On Tue, 30 Jun 1998, Leo Papandreou wrote: > On Mon, Jun 29, 1998 at 06:11:25PM -0700, Jordan K.
