Re: Host unknown
Daniela,
When you have a question like that, be sure to try to isolate applicaiton style functionality from base functionality.
In this case one might wonder whether sendmail is the victim or the cause.
So you try some other things, notably PING and nslookup and stuff. Perhaps your dns/bind server is not set up correctly.
Can you ping or sendmail to other hosts which are not in the local /etc/hosts files.
And, can other systems ping this hola.com.
What address is returned? Can you ping/sendmail the numeric address from Unix?
Finally it may be important (or not) to exactly which OS and which version you are using.
Hein.

Re: Host unknown
A quick solution is to edit /var/sendmail/sendmail.cf and replace mailer.hola.com by its ip address enclosed by [], for example instead of:
DSmailer.hola.com
configure
DS[192.168.0.1]
DSmailer.hola.com
configure
DS[192.168.0.1]
