Mail send, but ECONNRESET Error

[Biomido]

Hello,
Great project !

I have a problem with random ECONNRESET errors thrown after mails been successfully sent.
Most of the time this happens, in like 1/6 trys there is no error.

Node version is 9.4

The error message:

        recv mail.ch>221 Bye
        OK: 221 221 Bye

        null
        '221 Bye\r\n'
        send mail.ch>
        fail to connect mail.ch
        Error: read ECONNRESET

            at QueryReqWrap.onresolve [as oncomplete] (dns.js:245:10)
        undefined

The used code:

            const sendmail = require('sendmail')();

            sendmail({
                from: '[e-mail]',
                to:   '[e-mail] ',
                subject: 'random title',
                html: 'random text'
              }, function(err, reply) {
                console.log(err && err.stack);
                console.dir(reply);
            });
