lib/mailer.service.ts#L23 private to public?

[junxiaotan]

内部一些privaite属性，建议改为public，例如 transports，我想通过这个实现如果已有就不再xxxx。

Maybe I can implement a function to get the transports, what do you think?

I'm open to suggestions

[junxiaotan]

Sure！ as long as it can be exposed, it's good

We need a way to access the transports to be able to use Nodemailer plugins by doing transport.use('compile', plugin). I see two ways of doing this:

1. expose the transports
2. accept a list of plugins to add:

{
  /** whether to add the plugin before or after the template compilation plugin */
  position: 'append' | 'prepend';
  /** First parameter to be used in transport.use(step, plugin) */
  step: 'compile' | 'stream';
  plugin: import('nodemailer/lib/mailer').PluginFunction;
}[]

Also, both can be done at the same time. This would make it easier to add plugins via configuration and allow other advanced use cases by directly accessing the transports.
