With regard to my earlier posting on my homebrewed scheme for dynamically
changing the local hostname when connecting to my ISP, Todd Weible remarks:

Well, if what you're doing works, then I agree; there's probably no
good reason.
I do it because:
1) some aspects of my personality are "tidy". If my machine has a
name within the global internet domain, why not use it?
2) I noticed that without setting my name to match the domain given
in the /etc/resolv.conf file, sendmail was delaying several minutes
before sending mail outside the machine. With a hostname matching
the domain, sendmail sends out immediately. This is useful if I
want to send mail, then immediately shut down the link and go somewhere.
But hey, I can see why these reasons would not seem compelling to everyone.
