Suppose I have a PPP connection to a host, and I am assigned an IP address dynamically. Can someone send me mail to my PC via that temporary address while I am logged in? Right now, for instance, I have been assigned the IP address 126.96.36.199. From some other system, can someone send me mail as firstname.lastname@example.org, assuming harlow is a valid userid on my PC?
I don't have an officially assigned domain name for my machine, so that isn't an option. I have the machine set up with the name jeh.linux.org and IP address 192.168.0.1, which (according to NET-2/3 HOWTO), is available for internal use only.
I normally receive mail at my system at work, but when I am home and using Linux, I would like to be able to forward incoming mail directly to the PC. Any suggestions?
