Mail (MX) Server Survey
February 1st, 2018

Report Description
This report is a comprehensive report involving all mail servers we know of visible on the internet. For each domain in our conventional web server survey, we also determine the list of mail servers that provide inbound mail services (via MX record lookups). Each unique mail server is connected to once each month, where we wait for the server's "220 " message which usually accompanies a banner revealing the server software being used.

Basic Response Statistics
When connecting to an MX server, a number of different responses are possible. The remote server may not be up and running or completely refusing connections, it may not respond back with a "220 " line in the amount of time we wait, nor will it always provide a banner that identifies the type of software running.
