First, a little SQL
The first PL/SQL script does a pattern check for common errors, such as : hotmial.com, invalid domain, etc.
The second SQL*Plus script generates a list of addresses and User IDs, to be used in Web Link Validator

3. A bit of massaging in TextPad
For Web Link Validator to work, the list of s must look like a web page; TextPad can be used to quickly add html tags:
Use Fill Block to add html tags
