Re: [Exim] Two questions (solved ?)

Hello !
I think I solved my one problem:
a piece of my config:
sender_address_relay="*@lsearch;/etc/exim/aliases/domains"
#this for outgoing relay

local_domains=/etc/exim/aliases/domains
#this for incoming

host_accept_relay="*"

I cannot base my relay-check on IP or hostnames, because my company provides
mail for many people.
In the future I plan to implement SMTP AUTH command - is it hard to configure
in exim?
But the second question is open:
Wildcard MX for my domain
Subdomains listed in file (for example /etc/exim/aliases/domains)
How to customize exim to accept mail for listed subdomains, but refuse with
kind message for other?
