eMail + DevonThinkPro

I need a link to a document that explains in detail what DevonThink can do with eMail. I would like to use DevonThink as my local mail archive. Can I do that? I would like to be able to put certain email into DevonThink for follow-up folder and delete the email from my inbox inside (MailMate/imap), can Devonthink do that? What happens if I want to reply to an email later, can DevonThink do that?

I keep hearing that DevonThink and eMail can work together, but when I look in to it, I can not find any real sense of what really happens to the email and what can be done with it. I am using DTPro3

If I were you Iā€™d start with the incredibly comprehensive manual which you can download here.
