A 200 implies a valid inbox and anything else implies either an error with our connection to the mail server, or a problem with the address requested. This is where, based on the response from the mail server, we are able to conclude the deliverability of a given email address. The last, and obviously most important step in this process is the RCPT command. We then identify ourselves as and set a reply-to email of (both these are configured via the SOURCE_ADDR environment variable). QUIT // Cancel the transaction, we have all the info we needĪs you can see we first form a tcp connection with the mail server on port 25. RCPT TO: // Set the recipient and receive a (200, 500, etc.) from the server MAIL FROM: // Set the FROM address being our own HELO // We identify ourselves as (set via environment variable) All that's needed to validate an address is to send a GET request using the below URL with one of our three supported formats (json/jsonp(with "callback" (all lowercase) queryparam)/xml).įirst a TCP connection is formed with the MX server on port 25. Please keep in mind, self-hosting Trumail requires bidirectional communication on port 25 which most residential ISPs restrict - AWS and Digitalocean both permit this sort of communication. NOTE: While we do offer a managed, enterprise level service to paying customers, it is highly recommended that you host the service yourself either using a Docker image or by forking and serving this project on your own instance. It is available in three forms, the Golang client library verifier for use in your own Go projects, a public API endpoint (more info: ), and a public Docker image on DockerHub (see: ).
