nodemailer 在koajs 中如何解决？

问题链接https://github.com/koajs/koa/issues/433 //smtp.js

var cSmtp = require('../server/config').smtp,

    nodemailer = require("nodemailer"),

    smtpTransport = require('nodemailer-smtp-transport');


module.exports = function (mailOptions) {

    cSmtp.secure = true;
    cSmtp.debug = true;
    var transporter = nodemailer.createTransport(smtpTransport(cSmtp));

    mailOptions && (mailOptions.sender = cSmtp.host);

    mailOptions && (mailOptions.subject = '[通知]Docs.ren提醒邮件');

    var smtp = new Promise(function (resolve, reject) {
        transporter.sendMail(mailOptions, function (err, info) {
            if (err) {
                reject(err);
            } else {
                resolve(info);
            }
        });
    });

    return smtp;

}

//Calling

//failure prompted 500????
//当用yield ,在reject的时候会报500错误，如何解决
var sendMail = yield smtpMail({to: email, html: yield ctx.render('smtp', content)});
            console.log(sendMail)

//notes block, this.body not executed
//当用这种方法时，this.body 不会执行，直接404
                //smtpMail({
                //    to: email,
                //    html: yield ctx.render('smtp', content)
                //}).then(function(){
                //    console.log(1)
                //    ctx.session.pwdKey = content.key;
                //    ctx.session.sendemail = content.email;
                //    ctx.body = {
                //        msg:'邮件发送成功，请尽快查收，更改密码',
                //        status:1
                //    }
                //    return;
                //},function(){
                //    console.log(2)
                //    ctx.body = {
                //        msg:'邮件发送失败，检查网络并重试',
                //        status:0
                //    }
                //});

没人遇到过吗？只能先这样处理了，nodemailer 不支持 Nodemailer does not include out of the box support for promises or generators.

try{
                yield smtpMail({to: email, html: yield ctx.render('smtp', content)});
                ctx.session.pwdKey = content.key;
                ctx.session.sendemail = content.email;
                ctx.body = {
                    msg:'邮件发送成功，请尽快查收，更改密码',
                    status:1
                }
            }catch(e){
                ctx.body = {
                    msg:'邮件发送失败，检查网络并重试',
                    status:0
                }
            }
