nefunkcny mail

Zdravim vsetkych!
Mam tento problem. Nedaju sa mi poslat maily. Mam nastavene preposielanie kopii na inu adresu. Ked si poslem mail, tak sa vrati toto:

Hi. This is the qmail-send program at siva.anoweb.cz.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
