Can I set an environment var for SMTP mail servers? Pretty straight forward here, I'd like to use MailTrap for devMode and then use an SMTP service (Mandrill or like) for production. I looked through the General Config Settings docs but didn't see anything that lent itself to being SMTP related. Is this possible?
Not an easy way to do this in Craft 2, but this is possible in the upcomgin Craft 3 (currently in beta) using craft/config/app.php, which is multi-environment aware.
