Mail (MX) Server Survey
May 1st, 2024
Report Description
This report is a comprehensive report involving all mail<br>servers we know of visible on the internet. For each domain in our<br>conventional web server survey, we also determine the list of mail servers<br>that provide inbound mail services (via MX record lookups). Each unique<br>mail server is connected to once each month, where we wait for the<br>server's "220 " message which usually accompanies a banner revealing<br>the server software being used.
Basic Response Statistics
When connecting to an MX server, a number of different responses are<br>possible. The remote server may not be up and running or completely<br>refusing connections, it may not respond back with a "220 " line<br>in the amount of time we wait, nor will it always provide a banner that<br>identifies the type of software running.
