# INSTALL
# This assumes you already have qmail installed following LWQ (Life With Qmail) 
# http://www.lifewithqmail.org/ and Cyrus IMAP server http://cyrusimap.web.cmu.edu/ 
# and both are working.

# 1.) Rename the file to qmail2cyrus.sh and install it 
# to /usr/local/bin/qmail2cyrus.sh

# 2.) Read the orignal thread at http://rick.updegrove.net/qmail2cyrus/

# TODO: In order to use vpopmail and SpamAssassin to deliver to your IMAP INBOX
# Vpopmail strips environment variables so you have to use something like
# /usr/local/vpopmail/bin/vdelivermail "$DEFAULT"@"$HOST"
# Or you could just change your .qmail-default to (keep it all on one line).
# | /var/qmail/bin/preline /usr/local/bin/spamc -u "$DEFAULT"@"$HOST" |
#   	/usr/local/vpopmail/bin/vdelivermail '' bounce-no-mailbox


# First get the userid which is before the first dash.
userid="`echo "${LOCAL%%-*}" | tr "A-Z" "a-z"`"
# Then change dashes to dots
mailbox="`echo "$EXT2" | tr "A-Z" "a-z" | sed "s/-/./g"`"
if [ "$mailbox" = "" ]
    then
    # Use Cyrus to deliver to your IMAP INBOX
    /usr/local/cyrus/bin/deliver "$userid"
else
    # Use Cyrus to deliver to a folder (whatever Cyrus uses).
    /usr/local/cyrus/bin/deliver -m "$mailbox" -a "$userid" "$userid"
fi
# qmail is expecting exit codes so we have to deal with that.
