OK all you sendmail hackers, I have a (hopefully) easy question for you. I'd like to setup my router box so that it accepts and queus up email for machines in our domain when individual hosts (most notably our email server) go down. However, I *don't* want the email delivered to people on the router box, merely queued up until the main box comes up. I would think all I needed to do is add a MX entry to the nameserver to primariy point to the main email box, and alternatively point to the gateway box. DNS stuff for the mail machine; rocky.sri.MT.net preference = 0, mail exchanger = rocky.sri.MT.net rocky.sri.MT.net preference = 5, mail exchanger = sri.MT.net rocky.sri.MT.net inet address = 204.182.243.10 sri.MT.net inet address = 204.94.231.129 Rocky is preferred, but when it goes down our router box should get the email. And, the important DNS stuff for my router box. sri.MT.net inet address = 204.94.231.129 sri.MT.net preference = 0, mail exchanger = rocky.sri.MT.net sri.MT.net preference = 5, mail exchanger = sri.MT.net rocky.sri.MT.net inet address = 204.182.243.10 rocky is the preferred mail-host for addresses sent to 'user@sri.MT.net', so I needed to setup an MX record to make sure it got all the email for email addressed to 'user@sri.MT.net' First of all, does all of the above configuration look correct? Secondly, I don't want *any* email delivered to this box except for the email created locally (ie; cron scripts). Any external email should be 'queued' on the router box only until it's delivered to the real machines. Do I need to do anything on the router boxes /etc/sendmail.cf to have it 'Do The Right Thing'? I'm still getting errors like the below, but I don't want to add my hostname to the Cw macro since it delivers the the email on the router box instead of queueing it up. Either I have this mess below, or I have emailed delivered where it won't be seen. ----- The following addresses had delivery problems ----- <nate@sri.MT.net> (unrecoverable error) ----- Transcript of session follows ----- 553 gateway.sri.MT.net config error: mail loops back to myself 554 <nate@sri.MT.net>... Local configuration error Help! Nate
