I have found that Emacs + mu4e + offlineimap can deal with reading emails from a remote server. However, in this case, what I understand is that the emails are copied locally. Having mailboxes with lots of messages I do not want them to use hard disk space.
Did I misunderstand the way offlineimap works or is there another solution to what I want to do ?
I am new to Emacs, thanks in advance.
