mbork has a nice post on message-mode. The mode is meant to support email message editing. As mbork explains, there are several functions that make manipulating a message buffer easier. He’s using it with mu4e but notes that it’s handy with any mail client or even related applications. I especially like the quotation blocking function.
I really need to get mu4e working on my machine, at least for my irreal.org domain. Every time I start working on it, I get stuck trying to figure out how to get IMAP working with it. I know about offlineimap. Are there any other good solutions? This is for OS X.
