The best MailCatcher alternative is MailDrop, which is both free and Open Source. Other great apps like MailCatcher are MailGrab, Mailpit, MailHog and Mailcatch.app.
MailDrop is a free throwaway e-mail address. It's temporary. It's transient. It's disposable. It's meant for those times when you don't want to give out your real address. Just give someone any e-mail address in the maildrop.
