Personally I beleive that using your email address in certificates
is also a major problem.
The less computer literate users have a hard time distinguishing the
"mail virtual network" from the tcp/ip physical network and don't
really understand the difference between their mailname and the string
username(_at_)theirhost(_dot_)theirdomain
There are very many sites that don't seperate the mail name space from the
telnet name space. So they have multiple mailboxes with different names
depending on what machine they send the email from.
This is equally true for some of the non tcp/ip transported email systems.
Atleast X.500 /X.400 forms are divorced.
