Just Gnus does that kind of mess. None of clients in any GNU/Linux distribution is similar to it. The only cache that I know that some client may use is the IMAP header cache, for some 20000 emails in various folders it is now 55 MB. Principle of Maildirs is that they are files in a directory. It is questionable if cache helps there really. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns Sign an open letter in support of Richard M.
