Hi ALL,
respect 4 the project!
I start to configure ispcp after digit:
perl ./ispcp-setup:
Please enter a fully qualified hostname [mydomain.eu]:
here I've input my dns
and I've recived:
The hostname is not a valid domain name!
but sure is pingable, if I input onto browser my dns I receive:
It works!
suggestion?
