These can then be overridden by setting them explicitly. It sets IGNORENOCONNECT=on, CHECKOCSP=off, MXHOSTLIMIT=1, STOPAFTER=EHLO2, TIMEOUT=11, CACHEMIN=60, CACHEMAX=300.

This replaces the Confidence Factor with a Confidence QFactor, which may be a faster and better right-this-instant measure of security.

Quick Test Just do a quick 'yes' or 'no' test. All MXs are tested one after the other instead of at once, so we recommend using this option for just one specific MX. A MX test is displayed live in the browser as it happens. More Options adds these input fields: Show Test Progress Show MX tests in real-time. See the TestReceiver Full Documentation for more information about what the Detail levels show. Depending on the Output Level chosen it also shows what is inside the remote system's SSL Certificates and the details of the SSL connection established with the remote system. Detail is the log of TestReceiver's interaction with the recipient's email system. The next levels of output are all Detail. See the TestReceiver Full Documentation for more information about the MX Matrix stages.

Use the MX Matrix to look deeper into an email system, both down the matrix (by MX Host) and across the matrix (by stage), to show where strengths and weaknesses are in the system. The MX Matrix shows, for each MX host, how long each stage took and whether it was successful or not. TestReceiver groups the steps of sending an email into 8 stages. The next level of output is the MX Matrix. We suggest that a Confidence Factor of 90 or above indicates that the email address is 'secure'. with MTASTS and DANE testing) best-in-class email system would get. The Confidence Factor line shows the numerical grade of the target, the maximum grade the target could get, the grade's percent of maximum, and what grade a fully tested (e.g. It computes a single number for the given email address that is our opinion on how securely it will receive email. For domains with multiple email servers (MX hosts), it weighs how many there are and their preference. It takes into account all the security information gathered while it was connected with the recipient's email system. This is our 'grade' (zero to 100) for the recipient's email system. For all Output Levels TestReceiver shows our unique Confidence Factor.
