I usually don't install plugins that have so few active installations (800+ as of this writing) because I like my plugins well vetted so as not to cause me any problems. But after I reviewed all the alternatives, Mail Catcher was clearly the best option. I installed it in all my environments. I hope to never have email issues that will need me to use it but I feel a lot better knowing it is there if I do.
