The Nepomuk E-Mail feeder only indexes what is in the cache, and will therefore not index maildir folders. That means users who use POP will not have a functioning search.
Note that this only affects existing maildirs, not new messages that come in via POP3 while the feeder is running. And the same is true for (online) IMAP btw.
SVN commit 1124563 by vkrause: Allow to configure the initial indexing aggressiveness in three steps: only cached content, local and cached content (default) and everything.
