My home DSL has been down for over 48 hours and it appears that it will be down for several more days. (I spare you the gory details). I am concerned about losing mail coming into various domains at that site. That RH 7.3 machine runs mail/web/primary DNS for those domains. I have modified the secondary DNS records for those domains (on a machine at my office - also on DSL) with an higher cost MX record pointing to a machine at the office also running RH 7.3 and sendmail, which I assume will pick up and queue the mail. The DNS TTLs are reasonably short, fortunately. I've done this following O'Reilly/Sendmail book 2nd edition, but its not always crystal clear if you don't already understand it! Is there anything else I have to do on the backup machine (pointed to by the new MX records), particularly is there anything I have to do to its sendmail config files? Any other pointers or "gotcha"s to this whole process? Dick
