Subject: What Is Difference Between Internet And X.400 Style Names?

Can someone please explain the difference between X.400 and Internet-style
names of the form: USER@SITE.DOMAIN?  I had thought that X.400 names
were of the form /THIS=,/THAT=,/ANDWHATEVER=.  Recently, two things
made me question this.  First, someone told me that the USER@SITE.DOMAIN
was an X.400 standard.  Second, I noticed that PSI offers an X.500
service as part of their TCP/IP public data network PSInet.  Their
advertising literature seems to imply that the X.500 database holds 
addresses of the USER@SITE.DOMAIN type.  I understand that "bang" style
names are unique to UNIX (a derivative of UUCP), but are the USER@SITE.DOMAIN
style names X.400 or UNIX standards, and what is the relationship to
the longer addressing form /THIS=,/ETC=?

Thanks,
Will Estes        (apple!cup.portal.com!Will)
