E-Mail Addresses

All the UNIX cluster machines at PPPL use an address of the form username@pppl.gov. (@theory.pppl.gov, @carl.pppl.gov and @suntsu.pppl.gov, etc., also work, but shouldn't be used.)

All the VAXes, on the other hand, use an address of the form username@vaxmail.pppl.gov. Again, @rax.pppl.gov and@hax.pppl.gov also work but shouldn't normally be used.

The official PPPL forwarding machine is pppl.gov, which should be added as a suffix to every e-mail address to PPPL sent from off-campus. Usually, an address of simply username@pppl.gov is enough for the fowarding machine to find the addressee. Aliases for this machine include ppl.pppl.gov, pppl.pppl.gov, and pobox.pppl.gov.

Within PPPL, the extension .pppl.gov is optional. Thus, karney@vaxmail, and karney@ppl are sufficient. On the UNIX cluster machines .pppl.gov is also optional.

Finally, if you would like to mail off-campus, more information about Internet naming systems can be found in Section 7.4 [Internet Domain Name System] of the report, `Data Communications and Networking at PPPL' (by Jim Snyder). To find out more about sending and reading mail, see User-User Comm.
