{
"mail_host": "[ip]",
"port_opened": true,
"connection": false,
"errors": {
"mailfrom": "<ip> Service unavailable, Client host [ip] blocked using Spamhaus. To request removal from this list see https://www.spamhaus.org/query/ip/[ip] (AS3130).",
"connection": "SSL_read: unexpected eof while reading"
}
}
