Bug#782092: exim4-config: Support both local and full email addresses in /etc/aliases

[Victor Porton]

Package: exim4-config
Version: 4.84-8
Severity: wishlist

Dear Maintainer,

The default configuration of Exim in Debian should support both both local and
full email addresses in /etc/aliases .

For example the following should be valid:

joe: joe2 at example.com
john at ourserver.com: joe3 at example.com

There will not be such an option, ever. I guess. Since it's Exim's
approach to give you a framework to configure whatever you want, and not
to give you options such single purpose options.

You can use an additional router or you can use the "failing" branch of
the lookup in your existing router.

    system_aliases:
        …
        … = ${lookup{$local_part}lsearch{/etc/aliases}}

    full_aliases:
        …
        … = ${lookup{$local_part@$domain}lsearch{/etc/aliases}}


OR

    full_and_system_aliases:
        …
        … = ${lookup{$local_part@$domain}lsearch{/etc/aliases}{$value}\
             {${lookup{$local_part}lsearch{/etc/aliases}}}}

I think, the Exim specification contains examples like this one above.
