I have smtp auth set up on my exim4 Dqueeze server so that only auth'ed clients can use it as a mail relay.
I believe this is working, e.g. thunderbird (w/out password) reports that I am "not yet authorised to send mail for X from Y".
I also have greylistd installed, which I also see to be working.
But I've noticed that when an unauthorised connection is made the error is
temporarily rejected RCPT <email@example.com>: greylisted
Should greylisting be taking effect here? Surely it should just be saying "go away, you're not authorised" rather than filling up a greylist queue?
