> This basically means that you have on the order of milliseconds to accept or reject the email, so merely starting up a another replica of your SMTP daemon isn't going to mitigate this issue. The chokepoint is querying the list of users to see if you should bounce or accept the email. You don't have milliseconds. You can take quite some time to handle the client. 10s of seconds for sure. For example default timeout for postfix smtp client when waiting for HELO is 5minutes. |
