I used to do this with a ppp-connected computer earlier. The general thought is to force a MX(nameserver) check of the destination address of all mail and to make sure your own computer is not used for this. Sendmail will then fall back and try the secondary MX server which should be some name-server you trust to be up all the time. It is also important that the name and ip-address of this server is also present in your /etc/hosts file. I've modified /usr/src/sendmail/cf/debian-local.mc to do this. (Beware, I haven't tried this, as I'm presently without ppp-connectivity. ----8<---- divert(-1) # # deb-local.mc # # This is what you should use to create your site's configuration. # That way you don't have to destroy the examples. # # Jonathan Rozes <[EMAIL PROTECTED]> # include(`../m4/cf.m4') OSTYPE(debian)dnl MAILER(local)dnl FEATURE(nouucp)dnl MAILER(local)dnl MAILER(smtp)dnl define(`confBIND_OPTS', True) define(`confMESSAGE_TIMEOUT', 365d/1h) define(`confFALLBACK_MX', samson.misjonshs.no) define(`confAUTO_REBUILD', True) ----8<---- Compile this and copy the resulting file to /etc/sendmail.cf. Messages will be queued since it can't connect to the name-server, and you might want to run sendmail -q to make sure they are sent when you are connected. (If you use ppp this could be acomplished in /etc/ppp/ip-up) If anyone try this, please don't use samson.misjonshs.no! Vebby
