Testing email in a staging environment has always been scary. Production is easy because it actually sends, and local is easy because it saves to a file. But if we want to see what happens between development and production, and if we want to see how it looks in an email client, then neither of these options works very well.
Until tonight we’d just been really careful about which accounts were used. Now we have a server that accepts any email sent to it and delivers it to one mailbox. No more time bomb ready to explode unsuspecting clients’ inboxes.
