I have a sendmail message error when I send a mail :
"My unqualified host name (myhostname) unknown; sleeping for retry"

My mail is send but after a long time.

I know that I should add in /etc/hosts the line : machine.domaine.fr localhost myhostname

But I can't because others application (samba, sge) would fail.

I tried to had : dnl define(`confHOSTS_FILE', `/etc/hosts.sendmail')dnl in the config.mc file but it is doesn't work and had the good line in this file. Sendmail still read in /etc/hosts file.

What can I do ?
