[Exim] New Exim User

Good evening All,

I am replacing my main email server and would like to use Exim rather than
Postfix which I have been using previously.

I am going to settle down with the 4.2 specification .pdf later but I wonder
if anyone could give a quick overview of a couple of points for me to help
me get started?

I use an aliases file to control local email addresses and assume that there
will be a very similar file for Exim?

I use a virtual file (db) which has the format

simon@??? simon
sales@??? someonesales, simon, someone@???
@domain.org domaincatchall

I also hope that there is a similar file for Exim?

Simon
