Hello Todd, 

Thanks for your answer. 
Should I build my own DNS server ?

Notes the domain cimpaca.unice.fr exist in the DNS
:~] $ dig +nocomments +nostats cimpaca.unice.fr                                 
                                       

; <<>> DiG 9.8.1-P1 <<>> +nocomments +nostats cimpaca.unice.fr
;; global options: +cmd
;cimpaca.unice.fr.              IN      A
cimpaca.unice.fr.       86400   IN      A       134.59.238.1
unice.fr.               86400   IN      NS      dns.inria.fr.
unice.fr.               86400   IN      NS      diamant.unice.fr.
unice.fr.               86400   IN      NS      taloa.unice.fr.
unice.fr.               86400   IN      NS      samoa.unice.fr.
taloa.unice.fr.         86400   IN      A       134.59.1.7
samoa.unice.fr.         86400   IN      A       134.59.1.1
diamant.unice.fr.       86400   IN      A       134.59.132.2
dns.inria.fr.           1651    IN      A       193.51.208.13

I tried to configure EXIM, for all adress coming out with cimpaca.unice.fr 
domain name. Each time I 've got the servername + domainname.

Could you give any idea?

Thanks for your help....
