seems simple enough ...  and i don't understand why it's easier
to type an email vs typing  john and fakepwd  and, after
posting to the list, one has the thrilling suspense of what the 
answers will be :-)

the other tests i would do is make sure ssh logins only work
from certain machines ...  that even if you know the right login 
and right passwd, you will not be able to login from any random
outside machine like the cracker's machine

even if they sniff your login and passwd .. they can't use it
unless they happen to break into the one machine that the target
trusted that it'd allow the incoming ssh connections
