It can be used to retrieve mail, despite its missing qualifications. And it must skip tmp, lest fetch rubbish. So there is a class of maildir readers which are neither mail retrieval agents nor mail user agents. > I modified the Wikipedia paragraph to say: > > When a maildir reading process (either a mail retrieval agent or a > mail user agent acting locally) finds messages in the new directory > it must move them to cur (using rename() - link then unlink strategy > may result in having the message duplicated) and appends an > informational suffix to the filename before reading them. What is still missing is the purpose. I grasp that MRAs and MUAs have a duty which rsync is relieved of, but why? (A similar duty is to delete any old file left behind in tmp. This is just housekeeping which any process can do.) Rather than classifying maildir readers any further, it may be clearer to explain, say, that such new-cur split is/was meant to ease some sort of operations, such as client-side spam filtering. IMAP and POP3 client don't seem to need such functionality, so it must have been something related to local MUAs. Is that right?
