I'd like to know:
If there is a tool to create a large list of fake email addresses for checking autocomplete. I want to check it with data, it looks like it could be real ..?
If someone knows how large the list can be (approximately) in memory for autocompletion, it will still function using only Javascript in the browser. When will I need to do this using a database (server side)?
You can use mailinator.net addresses. This is temporary mail addressed to mailinator.com to avoid sending your own account.
db ,
test1@mailinator.net, test2@mailinator.net etc.
