Re: Re: chkuser - rejects legit mail, when followed by bad e-mail

It is not clear to me if the same message is sent to multiple users, or 
multiple messages to multiple users using the same smtp session.

BUT, I think, if the *last* email rcpt is legit, then the message is 
passed along to that legit account irrespective of any any failures that 
happened before. I will have to review the mail log to see if thats true.

I will have to log the smtpd session to see what the actual conditions are.
