I often add new (mail) users to my webserver. New users don't have a Maildir yet, it is created by postfix the first time they either receive or send email. And this of course, can take a while.
But when they try to login to RC while Maildir hasn't been created yet, the browser hangs and I see an apache instance on my server eating up 100% of my CPU cycles. Each login retry will create a new instance of apache. This can easily be exploited and bring a server to its knees.
Is there a solution for this? Is this a bug? Will this be solved?
