In most recent versions of Smartermail, they implemented SignalR to keep the connection alive, which resolved a logout issue users were facing. However, now they are logged in forever (up to 60 days) and never automatically logged out.
This in general is bad security practice. I'm requesting to ADD a timeout setting where we can specify how many minutes of inactivity before it times out and logs the user out of webmail.
We have some IT guys just pulling their hair out because of this.
