I am interested in this. But my question is, why make your hostname match
the one the ISP is using? If it is always changing, you cannot give it
out to anyone. I guess I just can't see the advantage over what I do
which is assign myself a bogus domain name for no real reason, I
configure sendmail to have the appropriate configuration, and if I want to
log in to my machine remotely, I just telnet to my ISP, check my IP, and
telnet to it.
Anyway, please let me know what advantage there is in having the domain
name of your machine match the name assigned to you.
