I was okay with the Password Recovery options and not being able to view Passwords at all, but I was working under the assumption that was because Passwords in v15 were Salted & Hashed in accordance with Industry Standards and were not reversible.
Obfuscation through Obscurity is not really Security. As long as they could be recovered through third-party Apps using the API means it didn't really matter that they were hidden from System Admins or Domain Admins, as they were still recoverable in some form, and not really in compliance.
So, I for one, am at the same place I was before and after the change. I know that many people are happy about being able to set their Smartermail installation to allow Passwords to be revealed, but I would much rather have it to where Passwords couldn't be revealed by either Smartermail or through a third-party App using the API, where they were properly Salted & Hashed, and truly secure.
