My email address reachability is "unknown", its a fastmail hosted account. Quite a commonly used service.
Is an unknown classification supposed to be treated as "I don't know, probably safe" or "I don't know, probably don't accept it" ?

It's probably a good idea to use an email address you own as the from address if you want to use this in production, eg: "testing@mycorp.com", to avoid this grey-listing.

"input": "testing@example.com",
"is_reachable": "unknown",

} "smtp": {
"error": {
"type": "SmtpError",
"message": "permanent: The host name specified in HELO does not match IP address."
