# Autorespond using IMAP on Uberspace 7 (U7)
############################################

# Date: 2018-06-07

# Abstract:
# This script allows you to enable the autoresponder by creating an IMAP folder
# called "Autorespond" in the root of your IMAP folders (not in INBOX, but as
# a sibling of INBOX).
#
# Once the folder is present and it contains a message, the autoresponder is
# turned on and it will respond with the most recent message in this 
# folder. 
# 
# Limitations:
# Notice that I couldn't find a way to turn off quoting of the original message.
#
# How-to:
# In the following script, we assume that you have created a mail user test: 
# 
# uberspace mail user add test
# 
# Just replace "test" with your desired mail user name in this script.
#
# We also assume that your E-Mail-Adress is test@stardust.uber.space
# Just replace stardust with your host's name (e.g. klemola, taylor, etc), 
# don't confuse it with the name of your Uberspace 
# (the one, you have chosen yourself).
# 
# If you are using an external domain, this will work as well. E.g. for
# test@mydomain.tld. You can specify test@mydomain.tld as the sender below as well.
# 
# You should create one filter file for each autoresponder
# sender email address separately.
#
# Make sure that each filter file has access rights 600, otherwise it won't work:
# chmod 600 .test-filter
#
# Make sure that you use UNIX line-endings in this file, otherwise it won't work.
#
# Create the file .qmail-test with the following content (including the pipe):
# |maildrop $HOME/.test-filter
# 
# If you want to debug the autoresponder, turn on logging 
# by uncommenting the following line.
# 
# logfile "$HOME/test-filter.log"


# Set the default Maildir
MAILDIR="$HOME/Maildir"

# Set the sender for the autoresponse
FROM="test@stardust.uber.space"

# If you're using a separate mail user (not the primary), we setup the MAILDIR
# accordingly
import EXT
if ( $EXT )
{
	CHECKMAILDIR = `dumpvuser $EXT | grep '^Directory' | awk '{ print $2 }'`
	if ( $CHECKMAILDIR )
	{
		MAILDIR="$HOME/$CHECKMAILDIR"
	}
}

# Autoresponder rule
# 
# Note: -N is useless when using -T replydraft. I couldn't find a way to disable 
# quoting when using this reply format. Suggestions are welcome.
# See http://www.courier-mta.org/maildrop/mailbot.html

cc "| mailbot -T replydraft -l '$MAILDIR/.Autorespond' -N -A 'From: $FROM' /var/qmail/bin/qmail-inject -f ''"

# Receive the mail (the original mail goes into your INBOX)
to "$MAILDIR"

Your Webmail Autorespond folder should look like this

Thanks, I was looking for a solution since qmail-autorespond isn't existent on U7 any more.

However, does your script cleverly exclude mails from mailing lists like qmail-autoresponder does, or does it reply to simply everything?

You can skip the -T replydraft -l '$MAILDIR/.Autorespond' part and write -t $HOME/autoresponders/response.txt -N instead.
The only thing you have to do is creating the directory autoresponders or whatever you prefer to name it. And the response.txt file of course.

Thanks for your suggestion.

In case you want to set the FROM header automatically (e.g. if there are multiple users that should be supported by this filter, the FROM address can be constructed as follows:

import EXT
import HOST
FROM="$EXT@$HOST"
