maildrop for Debian
-------------------

You should be able to run maildrop without making it your default system
MDA: just put "|/usr/bin/maildrop" in your ~/.forward file (including the
quotes).

Here's a short recipe on how to set it as a MDA in Exim's exim.conf:

Add this to the transports section (anywhere, order doesn't matter):

maildrop_pipe:
  driver = pipe
  command = "/usr/bin/maildrop -d ${local_part}"
  return_path_add
  delivery_date_add
  envelope_to_add
  check_string = "From "
  escape_string = ">From "
  user = $local_part
  group = mail

Add this to the directors section (at the end, order does matter):

maildrop:
  driver = localuser
  transport = maildrop_pipe
  require_files = ${local_part}:+${home}:+${home}/.mailfilter:+/usr/bin/maildrop
  no_verify
  headers_add = "Delivered-To: ${local_part}@${domain}"

That's it. It's not the only way nor the guaranteed correct way to make it
work, but It Works For Me (TM) :)

For Postfix, you should be able to make it work just by adding the following
line to your /etc/postfix/main.cf file:

mailbox_command = /usr/bin/maildrop

That doesn't enable any checking for ~/.mailfilter files, though.

Note that lockmail, maildirmake and deliverquota and the accompanying manual
pages have been renamed to include the ".maildrop" suffix, in order to avoid
conflicts and allow coexistence with courier (lockmail, maildirmake,
deliverquota), qmail (maildirmake) and potentially others. Alternatives
(symlinks) have been used instead, so you can choose which of the programs
you want to use by default, using update-alternatives.

maildrop and lockmail.maildrop are installed setgid mail so that they can
do mailbox locking in the /var/mail directory. setuid root is removed
intentionally, you shouldn't ever really need it and it poses a potential
security risk (as any other suid binary).

The o-r restriction on .mailfilter* has been removed in the Debian package.

TODO:
 * integrate better with qmail/sendmail/etc...
