Hey, Firstly I would like to say that this is an awesome package.

I would to request a set of methods to access the msg body for both html and alternative/text. Would this be possible?

Hey, you're welcome.

You can use the method GetMessage from Email struct to get a RFC822 formatted message.

If this is enough, it's ok, but if you want only the body, there isn't a method for that. I can achieve this in this week, PRs are welcome too

Thanks for the quick response!

Currently I am inspecting the entire RFC822 message.

I'm just thinking it may be beneficial to have some getters to inspect message headers, body, and attachments for testing purposes.

It's time to V3 so make all your ideas here: #53

I have another package for that, see https://github.com/OfimaticSRL/parsemail
