Now what about the harder part of getting sendmail to be the outgoing smtp host? In my setup I have a static IP address but I relay my outgoing mail thru my isps smtp machine. I do this by giving that host name as answer to Smart relay host: in Sendmail.cf Now I'll still be doing that but other feeder machines on the home lan will be sending to my linux box as there smtp smart_host. And it will then be channeled on to the isp smtp machine. Somehow I need to tell sendmail about all this, but really haven't a clue as to how. I looked over the sendmail faq on line, but didn't see a section that looks like it covers that particular usage. I don't really have an idea where to even start looking. Most of the ducumentaion on sendmail assumes the user is a real ip with internet machines and domains. Lots of lookups of various kinds flying around. I start reading things like MX reverse lookups, A records C records etc etc, and go all numb in the extremities (including head). I need to tell sendmail to relay mail from 192.168.0.0/24 or something like that, and m4 it into a sendmail.cf. But lack the voodoo incantations. _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
