2 edits | said by AstroBoy:The MTA standard is to return a warning after 4 or 5 hours. And return a failure after 5 or 4 days. Most MTAs (Qmail, Postfix, Exim, Sendmail) have a single variable: maximum queue lifetime. No messages are sent back to the originating email user until the queue lifetime is exceeded.
said by AstroBoy:I want the warning in 4 or 5 seconds. Without DNS redirection, you can get the warning in 4-5 seconds. If you find that you are mistyping e-mail addresses enough for this to be an issue, you probably want to focus your effort on improving your typing accuracy.
Of course, this really only presents an issue for home users running their own mail server that are also using their ISP's DNS service with redirection. As long as the gtld and other top level domain servers remain redirect free the Internet is in fine shape. |
