[Pkg-exim4-users] Newbie - Where to write marcos?

[Dermot Paikkos]

Hi,

Sorry if this is a dumb question.

I have opted for the split configuration and am trying to set a few 
values, namely LOCAL_DOMAINS and LOCAL_DELIVERY

I thought I should put these local variables in a separate file 
somewhere under /etc/exim4/conf.d.

Perhaps I have misread the README but I thought I could have a file  
/etc/exim4/conf.d/main/00_myserver_settings with this is:

LOCAL_DOMAINS=/path/to/list/of/domains
LOCAL_DELIVERY=maildir

Then if I update exim at some stage my local settings will be kept 
but that isn't working. 

Is it possible to maintain a separate file with local setting in? If 
so, how and where?

Thanx.
Dp.
