FAQ, by Marc SCHAEFER,
The internet domain system is based on domain servers, real time servers residing on known machines that know all the machines in a particular domain and how to get to them. When you send mail through an internet machine, like this (assuming you have a UUCP connection to UUNET):
uunet!caps.ibm.com!user
uunet (actually uunet.uu.net) will talk to the domain server for the .COM domain to find caps.ibm.com (a name I made up).
UUCP works differently. While the internet is a real time network, UUCP is a batch network. UUCP has what is known as a MAP entry for every UUCP site that submits one. If you are a new UUCP site just connected to your feed, you should send a MAP entry to the appropriate administrator. A MAP entry is *NOT* a domain entry.
The UUCP MAPS are used by machines on the USENET to find other machines on the USENET without the aid of domains. Not all machines on the USENET use MAPS to find some destination. uunet.uu.net does, so here is an example. I can send email from overload to (again, a made up name):
uunet.uu.net!fubar!user
Even if uunet does not talk directly to fubar.. assuming fubar has a MAP entry. uunet will search its maps to find the best path to reach fubar, and then route the mail accordingly. The actual route that uunet constructs might be: mcsun!gab!fubar!user
If your feed is a machine that does NOT use maps, then you must specify an explicit bang path to get past your feed to a site that does. For example, lets say your feed is named 'char00' and has a dumb mailer, but connects to harvard.harvard.edu via UUCP. You want to email me. you can do it in two ways:
char00!harvard!uunet.uu.net!overload!dillon.
or
char00!harvard!overload.Berkeley.CA.US!dillon
But, since your mailer is dumb, you would not be able to use:
char00!overload.Berkeley.CA.US!dillon
If, on the otherhand, char00 is a SMART USENET mailer that uses the USENET MAPS (but still isn't on the internet itself), you can use:
char00!overload!dillon
Finally, if char00 is on the INTERNET, you can use:
char00!overload.Berkeley.CA.US!dillon
