[Exim] Alias, then store.

Hi, all.

I'm using exim internet mailer, with the virtual domain configuration
found in config-samples. I thought Exim is running quite well.

As default, exim doesn't store a mail locally if the receiver's address
is in /etc/aliases file, but now we want to transport it and then store
it locally too.

Here is the real example:
My mail address is "wassy@???" as you see, and I want to
transport my mails to my mobile phone "wassy@???", but also
I want to read it on PC by communicating with "gens.co.jp" server
as the user "wassy".

I thought adding "wassy: wassy, wassy@???" to /etc/aliases file
will be okay, but it does not work.

Could we do that? And how?
I've given up. please help me.
