In sendmail I think the default retention time is 4 or 5 days. Usually plenty of time for service to be restored. After that it will return messages to the sender. The files you want to edit are relay-domains and mailertable, probably in /etc/mail. In mailertable you put in the domains you're accepting for and where to route the mail when the primary server becomes available. For instance you might have an entry like this: mikenoel.org esmtp:[192.168.5.17] The domain and address are purely fictictious of course. One would put in the IP of the mail server that should be accepting for that domain if it wasn't down for some reason, thus wouldn't use a non-routable address. Separate the fields with TABS, not spaces. After you've created/edited your mailertable you need to turn it into a db with the following command: makemap hash /etc/mail/mailertable < /etc/mail/mailertable (Don't be thrown by the input and output files having the same name. makemap will append an extension automatically so the output file ends up being mailertable.db.) In relay-domains you just put in the name of the domains for which you'll relay: mikenoel.org kevinmiller.org someotherdomin.org I think that'll about do it... ...Kevin --=20 Kevin Miller Registered Linux User No: 307357 CBJ MIS Dept.
