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.
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.
