Inbucket disposable webmail
Inbucket is an email testing application; it will accept messages for any email address and make them available to view via a web interface.
Why Inbucket?
Need to test your webapps outbound emails with Mailinator but stuck behind a firewall? Want to keep the new application you are developing secret until it’s time to release it? Need to validate that emails go out as part of your integration test suite? Want to send a link to a coworker demonstrating an email without giving them your gmail password? Need to load test your application without melting your corporate Exchange server? Want to use production data in your test environment without the risk of test messages leaking to an end user? Need to preview emails in multiple desktop email clients? Use Inbucket!
