Count unique domains in email list

This EnScript was written by request for someone doing an email spam case and he needed to parse a large list of email addresses and then extract only the unique domain names.

So in this case, he had a very large ASCII file containing thousands and thousands of email addresses, some of which came from the same organization and had the same domain, but different email address. He needed a way to just create a list of just the unique domain names. This EnScript takes an ASCII file, with one email per line, line-delimited with a CRLF like this:

john@test.com
dave@test.com
steve@test.com
mike@mydomain.com
tom@mydomain.com
joe@mydomain.com
etc...etc...etc...



The output of the EnScript in the CONSOLE tab would be:

test.com (2)
mydomain.com (3)

This is a pretty specialized EnScript, but others may have a use for it as well.
