https://github.com/mailhog/MailHog looks like a really nice alternative, where you can also test HTML mail, etc.

Personally, my local SMTP actually sends email, because I DO want legitimate email (mutt, cron) though, so I'd be scared to mix up two local smtp instances.

MailHog is pretty great. In response to your concern, by default it runs on a non-standard port, so you need to configure your apps to point at it (port 1025 by default). Even then, you can configure it to act as a MITM, where the webmail interface lets you "release" messages you actually want to send out: https://github.com/mailhog/MailHog/blob/master/docs/CONFIG.m...
