[Pkg-exim4-users] Adding a filter to send a copy of some mails, to an external mailbox.

[Nick Guerette]

One thing to be aware of is the value of dc_use_split_config in 
/etc/exim4/update-exim4.conf.conf ; if it is 'true', then you need to 
make configuration changes not in /etc/exim4/exim4.conf.template but 
rather in one of the files under /etc/exim4/conf.d/ .  The parameters 
you are setting do not go directly in update-exim4.conf.conf.  See: 
https://wiki.debian.org/Exim#Configuration
