dovecot - Jun 2010 - Auto forward virtual users mail using Sieve

Hi All

I'm trying to configure Dovecot to automatically forward mail to  
another account without the virtual user having to log-in first to  
Roundcube web mail. These are virtual users with no log-in to the  
server only Roundcube's web interface The situation is that I have two  
domains only who want to receive email at their domains, get a  
forwarded copy at their hotmail account, then log-in to Roundcube to  
reply.

  A Sieve script running in Dovecot seems the way to go, but the finer  
points of configuration have failed me.

I got as far as

1) /etc/dovecot/dovecot.conf
Adding:
protocol lda {
	mail_plugins = cmusieve
	mail_plugin_dir = /usr/lib/dovecot/modules/lda
}


2) /var/vmail/___domain___/___user___/.dovecot.sieve
Created the .dovecot.sieve file in the domain/user directory and added:
require 
["fileinto 
","reject","vacation","imapflags","relational","regex","notify"];
# Resend a copy of the message to another address
#
if true {
	redirect "julian at flatearth.co.uk";
}


Which doesn't seem to have broken anything. Or worked.

I'm assuming  that as   /var/vmail/___domain___/___user___/   is their  
virtual user home/mail spool the '.dovecot.sieve' file will get picked  
up.

It seems that Dovecot isn't configured to use send via Deliver ? My  
conf is pasted before

(Exim handles regular domain email forwarding mail for a bunch of  
virtual domains to pop accounts.)


TIA
Julian

Your MTA (Exim in this case, it seems) must already be aware of these virtual
user addresses since it accepts mail for them.  Adding a BCC to your MTA
config for these virtual users is the proper way to do this, not a sieve
script.  Not sure about Exim, but it's brain dead simple to do this with
Postfix' recipient_bcc_maps.  Since this occurs at the MTA level, users
don't
have to be logged in and it's fully automatic.  It's not a
'forward' but an
automatic blind carbon copy to the specified address.

There really is no point in troubleshooting a buggy version that is this
old.

Upgrade, and try again.

Use debian backports if need be - I have no clue why debian 'stable'
uses such old buggy software... but thats one reason I've never felt
inclined to try it.
