If you don't know mailinator.com, it a disposable email service with no passwords. Just pick any email address and you can check that email box. Emails stay in the inbox about 12 hours before being deleted. Lots of forums and sites have blocked it's domain though, since they don't like anonymous or spammy accounts, so I set up MX redirection from the domain we.lovebitco.in
to mailinator email servers. You can also do this with your unused domain names.
1. Go to mailinator, type a inbox name to check the email address mailbox,
2. You can use email@example.com
or the firstname.lastname@example.org
when signing up for spammy sites needing some email confirmation
3. send the mail box some test emails and check it out.
