My team uses mailcatcher, also, but (partly) for reasons I've not yet seen mentioned: Our primary application allows us to safely import recent dumps of the production databases into select CI systems, of which some tables have user records with real email addresses for report sending, etc. In the case that the code which sanitizes these records misfires or otherwise fails to do its job, at least we won't send random emails to actual customers. I know we've all gotten those from a vendor at one time or another and it's a corporate level face-palm that's worth the extra effort to avoid. Belts & suspenders, defense-in-depth, and all that.
