I have a couple of different tables in my SQL 7 database. One has a list of links (URLs), the other has a list of email addresses. I would like to write scripts that verify that an address is a valid one, and I'm really not sure what objects would present a potential solution. When I say valid address I mean that the address is not rejected by a server (by valid I do not mean 'legally correct'), so I suspect that the procedure would evaluate the response from a server.
An acceptable answer need not include any details on accessing the data; this is not a database question. However the answer should include either a code sample or a link to a page with a solution.
