Redhat 8.0 sendmail 8.12.5

[Dan Za]

Pouzivam REDhat 8.0 so sendmail. server pracuje ok ako mail server s pop 3
clientami.
Pri pokuse poslat mail priamo z terminalu servera mi pise toto:

[dano na gate dano]$ mail -v pupalaj na pobox.sk
Subject: test
Cc:
Null message body; hope that's ok
pupalaj na pobox.sk... Connecting to localhost.localdomain. via relay...
pupalaj na pobox.sk... Deferred: Connection refused by localhost.localdomain.
[dano na gate dano]$


Viete mi poradit preco mi neodchadza mail.
