#!/bin/sh
# /usr/local/sbin/toastercp.sh
# Copy qmail toaster domains onto another qmail toaster.
#
# Usage: /usr/local/sbin/toastercp.sh domain.com remote.mail.server.hostname
#
# CAUTION - this is only going to work if BOTH vpopmail-toaster installs were
# compiled with --disable-many-domains, otherwise, there will be a MySQL table
# mismatch and IMAP/POP authencation will fail. It's Okay to enable many
# domains, but again, BOTH servers must have already had vpopmail-toaster
# installed that way, otherwise you need to manually convert the vpopmail
# tables from one format to the other - which this script does not do.
#
#
# Change Log:
# Version - Feature
# -----------------------------------------------------------------------------
# 1.02 - Older mysqldumps don't write dump files to include dropping
# the tables being backed up, so now this script inserts that
# (this may produce MySQL warnings, as newer mysqldumps will
# have this, and therefore, complain that it can't drop a table
# that doesn't exist. Because .qmail-default files don't
# always exist, added find statements to not bother with it if
# it is not there. When using cpio to build a skeleton of
# files, find now looks for these files in the correct
# directory.
# 1.01 - Patches .qmail-default for the Unix pathname on the new mail
# server if catchall is set to another local e-mail address
# rather than catchall-to-bounce, catchall-to-delete, or
# catchall-forward. Not doing this results in maildrop
# creating duplicate messages in users' inboxes.
# Removes individual user .qmail files to cause qmail to
# re-create the file (sometimes, these files, when copied
# causes unwanted behavior when using webmail other other
# system features). The bad news is that this will delete
# any non-vpopmail based forwards (such as rules like forward
# and save a local copy).
# 1.00 - Initial Release
