You did not say that after the 2-4 characters the line should end...
End the pattern with $

You did not say it should be at the beginning.. everything can be in
front of the matching token. Start the pattern with ^
Also you are not escaping the . - meaning it can match to anything.
try it with this:
egrep "[EMAIL PROTECTED],4}$"
good source to read more about it is re_format(7)
