Very Computer

My Dell laptop is either online in one of two LANs where it gets its
IP number from DHCP, or from home via a modem.

I would like to let sendmail choose what relay to use, depending on
the IP number of the laptop.  This is to drop off the mail as soon as
possible to a machine that's permanently connected to the net.

Is it possible to hack the sendmail.cf file to do this?  Is this
possible to hack in an m4 file (it should be a simple satellite
machine with no address rewrites, talking to a hub, where the address
of the hub is different for different addresses of the satellite).

Thanx for any and all tips!

Somewhere there should be a script that runs when the ethernet/modem
interface comes up. This script could simply copy the proper file into
/etc/sendmail.cf, and then your sendmail will use the specified
smarthost.
