It works now.
It seems I missed the parameter 'dc_other_hostnames' in my exim4 config file.
I setup it to dc_other_hostnames='pc34ghz.org' (even if had same value 
in /etc/mailname ?!) which is my localdomain 

By 'it works now' I mean both following test work (as logged with 
user 'bruno'):

mail -s 'test001' root
mail -s 'test002' my_external_email at gmail.com

Note : emails sent to root are forwarded to bruno maildir as defined in 
aliases file

Thanks to all for attention.
Bye,
Bruno
