Ex: I'm sending a mail to xyz.com and my server could not connect to the xyz.com smtp server. My mail gets deffered and then it tries as per my setting but later another user of mine tries to send mail to the same domain and it happens again. I dont want postfix to try instead it can check the cache for the domain and not try delivering it.
Connection errors occur for any number of reasons, this is a common occurrence,and should be allowed for. You are asking for one such temporary instance to block all future mails? If gmail had a problem with one of their servers, you would never want to send to gmail again?
Please clarify exactly what problem you are trying to solve.
