Is there a way to allow sendmail to authenticate a user on a non-relayable ip?
For instance. I am travelling on the road and I use another ISP's dialup. Is
there a way to configure sendmail to relay from my IP if I authenticate and if
so could someone point me to the proper docs?
Just a curious question....
