Control of lock screen notification content

[davidra]

I am looking for an email client that will allow setting of the lock screen notification content. I have used iMailG for several years, which is a Gmail client that has a privacy lockscreen and also allows you to determine what shows up on your lockscreen notification, from "You have an email" with no identifying info, to full senders address and content listed. Unfortunately that app appears to have died since push no longer works on it. Is anyone familiar with another email app that had 1. password lock to access and 2. control over lockscreen notifications? Many have the first; I've not been able to find any with the second.
