UW-IMAP style mbox snarfing from /var/mail/ to ~/mbox

This configuration will move messages from /var/mail/%u to ~/mbox:

mail_location = mbox:~/mail:INBOX=/var/mail/%u

plugin {
  # add only the mbox file path here, no mbox: prefix.
  mbox_snarf = ~/mbox
}

protocol imap {
  mail_plugins = mbox_snarf
}
protocol pop3 {
  mail_plugins = mbox_snarf
}

If ~/mbox doesn't exist, nothing special is done.

If ~/mbox exists, it's treated as INBOX and mails are moved from /var/mail/%u whenever the mailbox is synchronized.

Before v1.1.8 if all the messages couldn't be moved because quota exceeded, then none of the messages were moved. v1.1.8+ just moves those messages it managed to move before running out of quota.

It's not possible to do snarfing between different mailbox formats. That would require a redesign of the plugin.
