My goal is to forward all local mail on my servers to a specific mail address. I have set up Exim4 in a satellite configuration on Debian Wheezy, however, exim4 ignores wildcards in /etc/aliases:
This wildcard is silently ignored by exim4. I could create hard-coded forwards, however, that's error-prone. I have no specific need for Exim4, however, I'd be interested in a solution which includes exim4, as it's installed on debian by default.
