Ask HN: open standards for mail storage?
https://news.ycombinator.com/item?id=1156033Hi all, I was wondering if there are any standards/documentation for storing mail, either in the server, or in e-mail clients? I am specially interested in how companies like Xobni are able to crawl the data from the user's mailboxes. A poor man's crawler could be probably with an IMAP client, but that doesn't sound particularly efficient.
