Jefferson Lab Electronic-Mail Addressing Convention

JLab Electronic-Mail Addressing Convention

Your standard email address at Jefferson Lab is of the form

yourID@jlab.org where 'yourID' is your computer-user account.

Most people can also use the form

Firstname.Lastname@jlab.org unless someone else on site has the same first and last names registered in CIS.

To determine what 'first.last' address is valid for any person, log onto a CUE UNIX machine and enter 'mailaddress' followed by a name or string to match. (The command is located at /site/bin/mailaddress.) The string will be matched anywhere in the person's name or user ID. For example,

      mailaddress jones

      Jones,Margaret (x1234  rm 13/124  ADMINISTRATION)
             msjones      Margaret.Jones

      Jones,Charles (x1235  rm 18/124  PHYSICS)
             ccjones      Charles.Jones

      Jones,Mike (x3234  rm 17/124 ACCELERATOR )
             jonesm       Mike.Jones

The first line for each item shows the name, as listed in CIS, along with phone, room, and division information. The next line shows the valid email addresses for each person. Assuming that there is no duplication of first and last names in the database, there will be a user ID and a FIRST.LAST name pair. Either form can be used for email, e.g., ccjones@jlab.org or Charles.Jones@jlab.org.

The next example shows a duplicate first-last pair, along with a valid match and the email addresses of alpha-numeric pagers for two people.

      mailaddress wilkins

       Wilkins,Lori (x7606  rm 12-L210  ACCELERATOR)
		      wilkinsl    Lori.Wilkins                   
		 wilkinsl-page    Lori.Wilkins-page              

       Wilkins,James (x7697  rm 19/124  PHYSICS)
		      jwilkins

       Wilkins,James (x7639  rm 19/186  PHYSICS)
		       wilkins
		  wilkins-page

In this case, the 'userID' forms (jwilkins@jlab.org and wilkins@jlab.org) are valid, but James.Wilkins@jlab.org is ambiguous as far as the computer is concerned. Mail sent using an ambiguous first.last pair will be returned to the sender.

Pager addresses will be listed on the third line for any person who has an alpha-numeric pager registered. The pagers will relay a message of about 80 characters, when the message is sent to one of the '-page' addresses. If someone does not have a pager, the "mailaddress" command will not list an address of that form.

Note that Internet mail addresses are not case-sensitive, i.e., any of the following are valid forms:

	    Charles.Jones@jlab.org
	    charles.jones@jlab.org
	    CCJONES@jlab.org
	    ccjones@JLAB.ORG
