Snarf Plugin
============

Requires v2.0.8+.

This plugin can be used to move mails from a "snarf mailbox" to user's real
INBOX. For example from '/var/mail/user' mbox file to user's final INBOX (e.g.
'~/mbox' or '~/Maildir'). Dovecot moves as many messages as it can until it
runs out of messages or out of quota.

Configuration
-------------

You need a default and a snarf namespace, for example:

---%<-------------------------------------------------------------------------
#mail_location = mbox:~/mail/:INBOX=~/mbox
#mail_location = maildir:~/Maildir

namespace default {
  prefix =
  separator = /
  inbox = yes
}
namespace snarf {
  prefix = /snarf
  separator = /
  location = mbox:/var/run/dovecot/empty:INBOX=/var/mail/%u:INDEX=MEMORY
  list = no
  hidden = yes
}
---%<-------------------------------------------------------------------------

Then tell snarf to get the mails from '/snarf/INBOX':

---%<-------------------------------------------------------------------------
plugin {
  snarf = /snarf/INBOX
}
---%<-------------------------------------------------------------------------

Use hierarchy separator as the first character in snarf namespace prefix to
make sure that there won't be any conflicts with user's mailbox names.

UW-IMAP style optional snarfing
-------------------------------

UW-IMAP does snarfing from '/var/mail/user' to '~/mbox' file, but only if
'~/mbox' exists. Normally Dovecot does the snarfing always if it's enabled. To
enable it only optionally, set also:

---%<-------------------------------------------------------------------------
# keep mail_location etc. settings as above

plugin {
  mbox_snarf = ~/mbox
}
---%<-------------------------------------------------------------------------

Now the snarfing is done only if '~/mbox' file exists. If it's not, the
'/var/mail/user' is used directly as the INBOX.
