Deno "dial" API changed

[stephdin]

The API for Deno.dail has changed (denoland/deno#3000)
According to https://deno.land/typedoc/interfaces/deno.dialoptions.html there is now a DialOptions object.

// smtp.ts:20:41
this._conn = await Deno.dial({
    hostname: config.host,
    port: config.port,
    transport: "tcp"
});

i can open a PR if you want :)

Of course, but I hope to change the READE.md and CI configuration together

@manyuanrong greeting. Are you planning to update your package, because it is not usable for now, unfortunately
