Have you removed the line

127.0.0.1 localhost.localdomain localhost

from your /etc/hosts file?

[Chrisssssss]

Thanks for your help
I have change this to my hosts file because if I remove this line my server( web,ftp, smtp, bind, pop3, mysql) stoped
127.0.0.1 localhost.localdomain localhost to 127.0.0.1 localhost but the problem is to continue and them receved this mail 40 / min
This is my /etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.


127.0.0.1 localhost
85.17.97.14 cip001.france-tracker.net
