I've seen a rash of multipart addresses recently, with the parts
separated by ".", and usually ending in EDU, e.g.
jsq@IM42.UTEXAS.EDU
userid@uiucuxa.CSU.UIUC.EDU
The first also said something about The ARPA INTERNET, while the
second appeared to be on usenet.
From left to right (after the "@") the format seems to be something
like   cpu.department.university.EDU
A brief explanation of this format would be appreciated.  Also, what
is EDU?
